Autosomal DNA Tests for Genealogy

First a disclaimer.  I'm very new to the whole world of genetic genealogy.  I'm not new however, to traditional genealogy, and I do have a pretty good amateur understanding of relative archaeological and anthropological discussions over the past fifty years.  The following is not meant as a critique of genetic genealogy, so much as a review, or my experience, of ancestry composition based on autosomal DNA analysis.

Let's start with my paper trail.

Traditional Genealogy

I am English by ethnicity, British by nationality, and a subject of Queen Elizabeth II (often now referred to as a UK Citizen).

My paper recorded ancestry consists of the genealogical records of:

  • Generation 1 has 1 individual. (100.00%)
  • Generation 2 has 2 individuals. (100.00%)
  • Generation 3 has 4 individuals. (100.00%)
  • Generation 4 has 8 individuals. (100.00%)
  • Generation 5 has 16 individuals. (100.00%)
  • Generation 6 has 29 individuals. (90.62%)
  • Generation 7 has 49 individuals. (76.56%)
  • Generation 8 has 35 individuals. (27.34%)
  • Generation 9 has 24 individuals. (10.16%)
  • Generation 10 has 10 individuals. (2.34%)
  • Generation 11 has 4 individuals. (0.39%)
  • Total ancestors in generations 2 to 11 is 181. (9.04%)

All 181 ancestors, reaching back to the 1690's, appear to be English born, of English ethnicity, with English surnames.  The majority of them (100% on my mother's side, and 81% on my father's side) were East Anglian, with the vast majority of that percentage being born in the county of Norfolk.  Religions recorded or indicated were CofE Anglican or non-conformist Christian.  No sign of any Catholicism, Islam, or Judaism.

Therefore it would look pretty likely, that I can claim English heritage, wouldn't you agree?

Genetic Genealogy and Ancestry Prediction

There are three aspects or avenues of inquiry, available for genetic genealogy.  First of all, the two sex haplogroups; the y-DNA, and the mt-DNA. These two "signals" are referred to as haplogroups.

  1. The y-DNA.  This follows the Y chromosome.  It is only carried by men.  It is passed along the paternal line, and only by that line, from grandfather, down to father, down to son, until the line is broken.  What a lot of people do often misunderstand, is that it does not represent 50% of your ancestry.  It does not represent all of your biological father's ancestry.  For example, his mother's father, and her brothers, although on your father's side, would most likely carry a different y-DNA haplogroup.  It only comes down an uninterrupted strictly paternal line.  Even at Generation 7 (g.g.g.g grandparents) above, it would have been carried by one out of my sixty four biological ancestors at that generation.  The other thirty one g.g.g.g grandfathers for that generation may have carried different Y haplogroups.
  2. The mt-DNA.  Although a very different type of DNA, this one works as the opposite sex haplogroup.  It is a signal that is passed down the strictly maternal line, from grandmother, to mother, to her children.  Yes, we men do inherit our mother's mt_DNA, but we can't pass it down.  Only our sisters can.
  3. The au-DNA, better known as Autosomal DNA.  Whereas the former two sex haplogroups are handy, because we can measure their mutations, and track their formation and movement across thousands of years, au-DNA really is the stuff that we are made of - all of the SNPs on our chromosomes that personalise us within the human genome.  We inherit our au-DNA from all of our recent ancestors.  Roughly 50% from our biological mother, and 50% from our biological father.  Equally, we could say on average, 25% from each grandparent, or 12.5% from each great grandparent.  However, it is messy.  At every reproduction (meiosis), it gets messed up by recombination.  Not only that, but go back much more than six generations, and it becomes more and more likely that you can lose entire lineages.  You can have no surviving trace of any DNA from for example, a particular g.g.g.g.g grandparent.

Autosomal DNA is what makes us individuals, gives us our hereditary traits.  It is passed down from many ancestors, via our parents.  However, the sex haplogroups are of interest because they can be traced across the globe, and the millennia.  As we gain more and more data - both from living populations, and ancient DNA from archaeological finds, so we will be able to track the STR and SNP mutation data more precisely.

However, what about poor old messed up autosomal DNA?  It represents our entire biological heritage over many generations. It is what we are. However, making sense of it is less easy, less precise.  Genetic genealogists are making progress, but it is far less of a precise science than either of the haplogroups.  They use calculators, that measure the segments of DNA cross the chromosomes, looking for patterns that they recognise from a number of known reference populations.  From that, these calculators predict an ancestry.  Exactly what and when that ancestry refers to, does seem to vary from one calculator to another.  There is an argument that the precision can be improved if you also test close known relatives including at least one parent.  The results can then be phased.  I'm actually waiting for the results for my mother, so that I can see my own au-DNA ancestry results phased and corrected.

So lets have a bit of fun, and see what some of the calculators suggest for my autosomal DNA, at least before any phasing with my mother's DNA.  What do they make of my 100% English paper ancestry?

23andMe.com Ancestry Composition Standard Mode

99.9% European.

Broken into:

83% NW European

17% Broadly (unassigned) European

I think that's pretty cool.  As I'm getting to know au-DNA predictions, so as I'm learning to appreciate it when they get the right continent, and the right corner of that continent.  That is more than they could do a decade or two ago.  The prediction is correct, I am a NW European.  I'm not a West African, a South Asian, or a East Siberian.

23andMe.com Ancestry Composition Speculative Mode

100% European

Broken into:

94% NW European

3% S European

3% Broadly (unassigned) European.

Whoa, where did that South European come from?  It could just be a stray incorrectly identified signal, or it could be telling me that one of my ancestors, maybe around Generation 6, were from down south!  Lets break down the prediction further.  First, the NW European:

32% British & Irish

27% French & German

7% Scandinavian

But surely I should be 100% British & Irish?  Not only 32%.  I have my own ideas about this.  I think that although 23andMe claims that Ancestry Composition only represents the ancestry of the past 300 to 500 years (the so-called migration period, as sold to USA customers), that it gets confused by earlier migrations across their reference populations, including those during the early medieval period, and perhaps even some of those during late prehistory.  I've noticed that across Ireland and Britain, the further to the east, the more diluted the 23andMe British & Irish assignment.  People of solid Irish ancestry get between 85% and 98% British & Irish.  My East Anglian results, mixed between British & Irish, French & German, and Scandinavian, are actually rather more like those received by Dutch customers of 23andMe.

As for that Southern European prediction, how does that break down?

0.5% Iberian

2.4% Broadly (unassigned) South European.

Which if taken seriously, might suggest that I have an unknown Spanish or Portuguese ancestor around Generation 6.  If I did take it seriously that is.  I wonder what my mother's test will reveal?

DNA.Land.com Ancestry Composition

This is a third party site, that you can upload your 23andMe V4 raw data to, and see what their calculators predict for your ancestry.  It has recently had it's ancestry composition revised.  What did that make of my 100% English au-DNA?

West Eurasian 100%.

I like that designation, the amateur anthropologist in me prefers that broad designation over "European".  Broken down:

77% North/Central European

19% South European

2.4% Finnish

1.3% unassigned.

What?  Why not 100% North/Central European?  Finnish?  Did some early medieval Scandinavian settlers of East Anglia bring it?  Or is it a false signal?  Misidentified au-DNA?

That darned South European kicked in again.  I'm here looking at a biological cuckoo NPE (non-parental event) at around Generation 5 or even more recent!  Did a great grandmother secretly have a South European lover?  But this South European breaks down further:

13% Balkan

6% Italian.

Oh my goodness, whereas 23andMe speculative mode suggested SW Europe - this one suggests SE Europe!  Do I have a secret Albanian great grandfather?  Or is it all nonsense?

WeGene.com

This is a cracking new third party DNA analyser.  It is based in China, and it's predictors appear to calculate mainly for a Chinese market.  It not only predicts your ancestry composition, but also your two sex haplogroups, and lots of traits and health predictions to compliment those of 23andMe.  It even tries to predict your genetic disposition to sexuality!

It will allow you to send your 23andMe V4 raw data direct to it's own calculators.  However, at the moment the website is almost entirely in Chinese (Mandarin?).  There are two options.  1) At the bottom of the webpages is a hyperlink to English, which gives, in English, a basic ancestry composition, and your haplogroups.  It does not include English versions of the health and trait results.  2) use an online translator, such as the one built into the Google Chrome browser.  It actually serves pretty well.

On sex haplogroups they give my Y-DNA as

L1.  Not bad, but they didn't make it to L1b or L-M317.

My mtDNA?

H6a1a8.  Very good.  Better than 23andMe's H6a1, and the same as the mthap program.

But this is about au-DNA, how did they do, what did they make of my 100% English ancestry?

81% French

19% English/Briton

Now, that sounds pretty awful, but on closer inspection, I'm impressed.  No South European great grandfather.  Okay, so most of my DNA has been placed on the wrong side of the Channel.  However, I know that French and English DNA is actually very close.  Recent surveys even suggest that the English have inherited a lot of common ancestry with the French during unknown migration late in prehistory.  So again - they very much got the right corner of the right Continent.  Well done WeGene.

GEDmatch.com Eurogenes K13

GEDmatch is a website that you can upload raw data not only from 23andMe, but from a range of testers, and from V3 chips as well as V4.  It hosts a number of tools and predictors - some Open Source.  Some of these predictors are for Admixture or ancestry composition.  They measure your ancestry in terms of distance from known reference populations.  The lower the number, the closer you are to their reference.  They use calculators known as oracles to predict ancestry, including mixed ancestry or admixture.

The oracles on the Eurogenes K13 and K15 calculator models have a good reputation at working with West Eurasian ancestry.  So how does K13 first, score my 100% English ancestry?

On Single Population Sharing, it rates my DNA against the closest references.  In order of closest to not so close, the top five are:

1 South_Dutch 3.89
2 Southeast_English 4.35
3 West_German 5.22
4 Southwest_English 6.24
5 Orcadian 6.97

I think that's a cracking result.  Okay, it thinks that I'm closer to South Dutch, than I am to SE English, but so close - and my East Anglian ancestry most likely does include a lot of admixture from the Low Countries from the early medieval period.  I really like Eurogenes K13.

Okay, let's now use the Oracle 4 option, to suggest admixture.  First on three populations admixing to create my DNA, what comes closest?

50% Southeast_English +25% Spanish_Valencia +25% Swedish @ 2.087456

Well that's interesting!  The SE English hit the net.  The Swedish?  Could be ancient Scandinavian admixture - but the Iberian prediction has reemerged!

On four populations admixing?

1 Southeast_English + Southeast_English + Spanish_Valencia + Swedish @ 2.087456
2 Southeast_English + Southeast_English + Spanish_Murcia + Swedish @ 2.147237
3 Norwegian + Portuguese + Southeast_English + Southeast_English @ 2.216714
4 Danish + Portuguese + Southeast_English + Southeast_English @ 2.225334
5 Portuguese + Southeast_English + Southeast_English + Swedish @ 2.230991

Oh my goodness.  K13 agrees with 23andMe AC, that I have an Iberian link.  I'm now really starting to wonder.

Let's finish off by trying K15 on my 100% English ancestry:

GEDmatch.com Eurogenes EU test V2 K15


Using Oracle for single population first, the top five closest:

1 Southwest_English 2.7
2 South_Dutch 3.98
3 Southeast_English 4.33
4 Irish 6.23
5 West_German 6.25

Okay, I'm SE English, not SW English, but pretty impressive again.

Using the oracle 4 for three population admixture, what mix comes closest to my auDNA?

50% Southwest_English +25% Spanish_Castilla_Y_Leon +25% West_Norwegian @ 1.080952

That Iberian back again!

Top five mix ups of populations closest to me?

1 Southwest_English + Southwest_English + Spanish_Castilla_Y_Leon + West_Norwegian @ 1.080952
2 Irish + North_Dutch + Southwest_English + Spanish_Galicia @ 1.111268
3 North_Dutch + Southwest_English + Spanish_Galicia + West_Scottish @ 1.282744
4 Southeast_English + Southwest_English + Spanish_Castilla_Y_Leon + West_Norwegian @ 1.295819
5 North_Dutch + North_Dutch + Southwest_English + Spanish_Castilla_Y_Leon @ 1.304939

I can't help preferring the K13 results to the EU test V2 K15 - simply because it recognises me better as SE English, rather than to their SW English reference.

Conclusions

If anyone ever bothers reading this far too lengthy post, I hope that I have imparted the following lessons:

  • Don't expect DNA Ancestry tests to pin point an actual country of ancestry.  They're not no where near that good yet.  The populations of West Eurasia, and elsewhere, are actually all mixed up, or share a lot of recent admixture.  In addition, many European nation-states are quite recent inventions.  I've seen the borders of Europe change in my short lifetime.
  • Don't expect precision.  If for example, you are an American, and a 23andMe AC test suggests only 32% British & Irish, then you could actually have 100% English ancestry over the past 300 years!  We're so mixed up, that these tests are struggling to part and identify us by nationality.
  • If you are willing to share your raw data (there are privacy issues), then have fun trying out all of these third party calculators.  It's a lot of fun as you can see.  They rarely agree.  There are other tools on GEDmatch for example, where you can compare DNA along with .gedcom genealogical files with other users - and look for shared segments on the chromosomes.  You can also compare your DNA to that of ancient populations.
  • Treat au-DNA differently to haplogroup results.  au-DNA is very interesting, and represents so much of our ancestry, if we could just sort some of the mess out.  You can partially do this by phasing your results with those of close relatives.  It is worthwhile phasing with at least one biological parent, if you can.  However, haplogroup results, provide by their mutations incredible stories over much longer periods - thousands of years.  A different kind of genealogy.  As we gather more data, and reference it also to ancient-DNA, so it will tell us more and more about two lines of descent.  Perhaps even into historical times.

Giving up Ancestors

I don't have to give these two up. My great grandfather Fred Smith, holding the hand of his daughter and my late grandmother Doris Smith around about 100 years ago in Norwich.

Trimming the branches

I make mistakes.  Genealogy is rarely perfect.  A part of the fun of the pastime, is in validating, verifying, and proving descent.  Sometimes though, the desire to simply add branches and histories, overtakes the quality control.  I'm guilty of that.  I've recently made a number of mistakes in my genealogical research.  A very good researcher would not make those mistakes in the first place.  They would research methodically and carefully, recording every data, looking for correlations - before they accept descent.  I on the other hand, still have a lot to learn.  However, I am willing to sometimes go back, check, check again, and if I'm not happy, remove ancestors, remove branches, remove histories.

With my recent return to genealogy, and my baptism into internet genealogical resources, I've witnessed the pitfall of the new age of research.  Family History websites push other people's trees and research at you.  However, so, so many of those that I've looked at, are erroneous, poorly sourced, and copied around like a mutated gene.  I want to create an ancestral record and history that is better than that.  I have an awful lot of work to do.

My recent mistakes have been shameful.  I made the above mistake - allowing MyHeritage.com to add branches to a couple of lines.  On checking their sources, and researching for myself, I couldn't validate the connections.  I removed them.

I wrongly identified a service record as belonging to a great grandfather.  That one hurt.

I extended my paternal surname line with too much haste.  I grabbed at a probable ancestor.  Later checks revealed a doppelganger.  I've had to go back to the drawing board, removing three generations from that line.

I don't regret these mistakes.  I'm always checking for validity.  A good quality family tree is better than a massive, old, but incorrect record.  The fun is after all, in the research, and that seems to go on forever.

Number of ancestors report

I'm continuing to have some success in adding ancestors to the tree, while at the same time I'm verifying, adding sources and citations, and adding flesh to bones.  I've been hitting Ancestry.co.uk and FindmyPast.com pretty hard while I can.  I also sometimes use the NORS facility on the Norfolk FHS website.  Finally, I've collected my old paper records and certificates from my old days in pre-Internet genealogy.

In some cases I have removed some proposed ancestors.  During a moment of weakness, I allowed the My Heritage website to add some branches to my tree from those of other researchers.  I wont do that again.  Looking closely, and checking for sources myself, I disagree with the authenticity of them.  I also found that I was barking up the wrong service record for my great grandfather.  I'll learn by these mistakes.

New branches or ancestors that I've recently uncovered include the Particular Baptist Tovel family of Suffolk, and the Daynes of Garvestone, Norfolk.

I found another handy feature on the open source Gramps genealogy software.  A Number of Ancestors Report.  It generated the below stats for me.

I think that it is typical for a family tree - recorded ancestors as a percentage of the biological generation, really start to rapidly fall away from Generation 8 (G.G.G.G.G Grandparent Generation).  Until then, most of the missing ancestors are down to illegitimacy events:

Number of Ancestors Report 11 April 2016

Generation 1 has 1 individual. (100.00%)

Generation 2 has 2 individuals. (100.00%)

Generation 3 has 4 individuals. (100.00%)

Generation 4 has 8 individuals. (100.00%)

Generation 5 has 16 individuals. (100.00%)

Generation 6 has 29 individuals. (91%)

Generation 7 has 49 individuals. (77%)

Generation 8 has 37 individuals. (29%)

Generation 9 has 26 individuals. (11%)

Generation 10 has 16 individuals. (3.5%)

Generation 11 has 4 individuals. (0.4%)

Total ancestors in generations 2 to 11 is 191. (9.53%)

The Three Ages of Genealogy

The above image was made from an opportunistic photocopy of a photograph held by a second cousin.  it is a portrait of Samuel William "Fiddler" Curtis.  He was one of my sixteen great great grandparents, and was born at Hassingham, Norfolk in 1852.  He worked as a teamster - an agricultural labourer that drove a team of horses in the fields.

1. The Past - Record Office Genealogy.

This was how I did genealogy almost exclusively twenty two years ago.  It still exists as a method.  It is still the most qualitative, and traditional research method.  It could be represented by a pair of white gloves - the sort that many record offices and archives insist that readers wear, while handling conserved records.  There is of course a cost.  Some parish registers for example, will suffer from handling, regardless of the level of care.  Otherwise I would recommend that all present day genealogists should practice it from time to time - in order to reference to the most original documents, or simply for the experience of handling these wonderful links to our ancestors.  I remember reading some parish records that I knew had been personally kept by my parish clerk ancestors.  I visited county record offices in Norfolk, Berkshire, Oxfordshire, Wiltshire, and Glamorgan.  I visited archives and the GRO in London.  Genealogy meant leaving the house and travelling.

Twenty two years ago, Digital Genealogy was in it's infancy.  The "IGI" was on microfische.  Censuses up to and including 1881 were available on microfilm.  Some parish registers were just starting to appear in the microfilm/fische room, but for many, I had to produce my readers card, don the white gloves, and carry a soft lead pencil.  Good times.  But sometimes frustrating.I had many dead ends.  If an ancestor moved more than a few parishes away, and preceded a census, you had to either spend years looking in so many parishes - or rely on a bit of luck.  You could of course find other researchers with shared interests.  They would advertise these interests in the columns of genealogy magazines, and in printed annual directories.

By the time that my personal interest drifted away from genealogy, things had already changed an awful lot.  Many more records had been photographed onto film or fische - to protect the original records from a growth of interest in family history.  Here in Norfolk, amateur genealogists were encouraged to use the film/fische reading rooms, rather than access the original documents.  Although some negatives were hard to read, it was much faster than ordering and waiting in a reading room by a ticket system.  People were also increasingly using the Internet as a way of sharing.  The IGI moved online.  We were also using database software programs such as Family Tree Maker, and sharing our .gedcom files online.

I then totally moved away from genealogy totally, for perhaps 12 years.

2. The Present - Internet Genealogy

My interest in genealogy and family history returned after that long break way.  What had changed?  What do I think of the current scene?  So many documents have been digitally photographed, transcribed, indexed, then fed onto online databases.  It's incredible.  Within a few months, my family tree has grown and grown.  I've picked up so many dead ends.  The IGI has evolved into FamilySearch.org, an incredible free online resource.  National archives have growing online collections.  There are commercial online subscription based resources galore competing - Ancestry, FindmyPast, MyHeritage, TheGenealogist, GenesReunited, FamilyLink, Genealogy, etc.  FreeBMD grows.  We can not only browse the England & Wales census online, but since I started researching 22 years ago, we now also have 1891, 1901, and 1911.  With a subscription we can even view them from our homes.

It gets much better though.  So much has been transcribed and indexed - then added to databases.  This means that we can database Search for missing ancestors.  This is the greatest advantage to Internet and database transcriptions - this ability to find them, where we might not have looked.  Also to find new details, to flesh out the bones of our ancestors - military records, criminal records, transportations.  In the old days, we would have needed to either visit a number of difficult archives in London, or hire an experienced professional genealogist to do this for us.  This is the sort of stuff that can now be accessed by the amateur from the comfort of the home.  There is a lot that is positive about the Present.

What can be depressing is that the margin for error has not only increased through badly transcribed indexes, but the ease of Internet search, and of copying previous research - duplicating error has greatly increased.  When I uploaded a skeleton direct ancestral tree to MyHeritage, I was plagued by the website, to add other people's work to my tree. However, when I look at their trees, very often, I don't agree with their conclusions.  I see what I believe to be errors.  Wrong generations married up.  Desperate looking links from parents many miles away - that when I investigate them, I can't verify.  I've very quickly learned to distrust other people's online trees.  I'll use them only as suggestions to investigate.

3.  The Future - Genetic Genealogy

The title of this section is a bit of a tease.  I was a bit of a sceptic of genetic genealogy.  Even now, I feel that people wishing to use DNA evidence for extending family trees should in most cases, save their cash.  However, I can see that one day in the future, genetic genealogy could be a serious tool.  What it presently lacks, particularly outside of the USA, is data!  It can only work, when enough people have recorded and shared enough DNA data online.  Even then, for anything else than measuring quite close relationships up to say, second or third cousin, autosome DNA does not offer much to the genealogist.  Most of our DNA is autosome.  Very useful for checking for recent non-paternal events.  Useful for example, for finding close biological relatives.

What I think will be of more use in the future, will be haplogroup DNA.  The Y-DNA and mt-DNA, and then - only when many, many more people, have submitted and recorded their DNA.  Even then, it will not produce a family tree.  It will identify common biological relations between researchers and other submitters.  Y-DNA will increasingly tie to surnames - and also mark the non paternal events where the haplogroup jumps from one surname to another.  FamilyTreeDNA are the forerunners in that field, with their DNA Projects.  Surname and geographic projects link actual family lines to certain haplogroups, clusters of haplogroups, STR markers, SNPs etc.  It's a great idea, but it's in it's infancy.

Imagine a future though, where not only most researchers have registered DNA data, but that of past generations - parents, grandparents, and even ancient DNA from archaeological sites.  This is where genealogy overlaps with anthropology.  Traditional genealogy traces ancestors from recent centuries.  DNA haplogroups show promise for tracing the general movements, admixtures, displacements of ancestors from thousands of years ago.  At the moment, genetic genealogy rarely supports traditional genealogy - rather, it compliments it with very different material.  In the future though, as if we continue to tie more SNPs and STRs to actual family lines, it'll start to mean something more to the historical period.  Actual surnames will start to attach to clusters.  At least that is how I see it.  I'm sure that the shareholders of the DNA testing companies would also like us to see that vision.

My transported great great great grandfather

Discovery at Deptford

See page for author [Public domain], via Wikimedia Commons.  Not actually the Justitia, but the Discovery Prison Hulk also at Woolwich around about the same period.

I'm using my free 14 day trial at Ancestry.co.uk, to see if I can pick up any new details for the family history.  Whenever I see an ancestor suddenly disappear out of the records from his wife and children, I tend to think either desertion or death.  But this is not always the case.  Sometimes there is another reason.  That is the lesson of today's story.

Back in the pre-Internet days when I carried out much of my genealogical research, I came across a bit of a puzzle on my grandmother Doris Brooker's (nee Smith) side of the family.  According to a marriage register and a 19th Century census, my great great grandmother Ann Smith was born circa 1835 in Lincolnshire, as Ann Peach.  That was as far as I got back in the days of traditional paper based genealogy.  In recent months, with my return to Genealogy within the Age of the Internet, I made a break through.  She was actually born 27th July 1835 at Etton, near to Peterborough, to a David and Sarah Peach.  Her mother Sarah, had been born as Sarah Riches at Hockham back in Norfolk.  Later, Sarah returned to Norfolk without David.  She and her daughter Ann appeared as servants in Attleborough, Norfolk, where young Ann met my great great grandfather Robert Smith.  Sarah worked in Attleborough as a char lady or washer woman for many years after.  She never appeared to marry again, but did go on to give birth to a few more children, that went on to carry the Peach surname.

So where did her husband David Peach go?  They were actually married four months before the birth of Ann, at Holywell in Lincolnshire.  How Sarah ended up there remains a mystery.  Few of my ancestors moved as far at that time.  I have not so far been able to trace his roots.  I was trying to do so, when I just browsed on the records at Ancestry.co.uk, that answered the question, where did my great great great grandfather David Peach go to?

The sources of the answer?  The UK, Prison Hulk Registers and Letter Books 1802-1849, and England & Wales, Criminal Registers 1791-1892.  David Peach had been convicted of cattle stealing in an assize court, on the 15th  July 1837.  He was found guilty. His punishment for the crime was Life Transportation.  In this case, it appears that he was first sent to serve as a prisoner, on a prison hulk ship, moored at Woolwich, London.  The ship that was to serve as his temporary prison, was the Justitia.  The prison hulk registers of the Justitia, record that he was 30 years old, was married, had stolen two steers, was literate, and was a shepherd by trade.  He had been incarcerated on the 27th September 1837, shortly after his trial in Lincoln.  Prisoners on the Justitia faced hard labour there, while awaiting transportation.  The prison hulk had been originally launched many years earlier as an East Indiaman named the Admiral Rainier.  It had been converted into a gun ship, an gun store ship, then finally, the old hulk was moored at the Woolwich Warren, and used to hold convicts in preparation for their transportation.

David was not held in the Justitia for long though.  On the 4th October 1837, he boarded the Neptune for transportation to Van Diemen's Land (Tasmania).  This was a 644 ton merchant ship built in 1815.  According to her Wikipedia entry: "On her first convict voyage, under the command of William Ferris and surgeon Joseph Steret, she departed Sheerness on the 7 October 1837 and arrived in Hobart on 18 January 1838.[3] She transported 200 male convicts, three of whom died en route.

So that is where he went!

Did my transported ancestor survive the voyage?  Yes he did.  In 1841, he was recorded in the New South Wales and Tasmania, Australia Convict Musters, 1806-1849 list, as police number 1404, a convict from the Neptune, who was employed in service at the Port Arthur Convict Settlement in Tasmania.  According to the Wikipedia entry for Port Arthur: "From 1833, until 1853, it was the destination for the hardest of convicted British criminals, those who were secondary offenders having re-offended after their arrival in Australia. Rebellious personalities from other convict stations were also sent here, a quite undesirable punishment. In addition Port Arthur had some of the strictest security measures of the British penal system.".

On the 18th July 1851.  David, residing at Longford, Northern Tasmania, was issued a conditional discharge.  He survived his transportation, forced labour, and life in a harsh convict settlement.  Did he manage to return to England?  I see no sign of him with Sarah.  My guess is that like many, he settled as a free man in Tasmania and died there.  I see no record of a ticket for leave.

Meanwhile back in England, his wife Sarah Peach nee Riches, and young daughter Ann Peach, returned to Sarah's family, who had moved from Hockham to the nearby market town of Attleborough in Norfolk.  Sarah had to survive and rear their daughter Ann with no husband.  She worked hard over the years as a servant, washer woman, and char woman in Attleborough.  She gave birth to at least two more children that carried the surname Peach.  One she christened as David, giving him his biological father's surname (Wilson) as a middle name.  She appears on the records as a hard working, strong, and independent woman.

Their daughter Ann went on to meet and wed local Attleborough boy Robert Smith.  For many years, they jointly ran a beerhouse in Attleborough named the Grapes.  Robert also worked as a bricklayer, and ran a builder supply yard from behind the Attleborough inn.


One of their children was Frederick Smith.  As a wheelwright, he moved to Norwich.  There he met a servant from South Norfolk called Emily Barber.  They married, and reared a family.  The youngest child was a Doris Emily Winifred Smith.  Her father would take her on business to East Dereham, where she met a young Reginald John Brooker.  End of this story.


The Thackers of Norfolk

The above photograph is of my Great Great Grandmother Sarah Anne Elizabeth Thacker (nee Daynes), of Rackheath, Norfolk.

I'm writing this for someone with shared chromosome segments that I've met on Gedmatch - my first potential relative, found through DNA comparisons.  She's in the USA, and has Thackers - which may be a link.  It's not that a common surname here, and very East English.  It has been suggested that the name is an Anglo-Danish variation of Thatcher.  I'm not so sure that it is of any Norse origin.  However, the strongest concentration of the surname in Britain today, is in the Dane Law county of Lincolnshire.  My Thackers though belong to a secondary cluster - also in the Dane Law, the region of East Anglia.

Thacker Family

I'm going to propose an estimated birth year of circa 1762 for my G.G.G.G.G grandfather John Thacker.  He first appears on my genealogical record on 2nd February 1787, when he married Mary Clarke at Rackheath in Norfolk.  However, tragedy struck.  Mary died a few years later in 1740, and was buried in the neighbouring parish of Salhouse.

John wasn't a widow for long.  He married my ancestor Ann Hewitt on the 26th April 1791 at Salhouse.

I have found records for three of their children.  Thomas Thacker was born in 1793, my G.G.G.G grandfather William Thacker was born 1796 at Salhouse, and his little sister Mary Thacker was born in 1801.

William Thacker married my ancestor Catharine Hagon at Rackheath on 19th May 1819.  Catharine gave birth to at least three children - William Thacker in 1820,my G.G.G grandmother Susan Thacker in 1823, and Thomas Thacker in 1825.  Their children were all later baptised at Salhouse Particular Baptist chapel.  I have very few Baptist ancstors.

William was an agricultural labourer, a farm worker by trade, as were the majority of my 18th and 19th century male ancestors.

Catharine must have died sometime between 1825 and 1833.

On 1st December 1833, William Thacker, now a widower, married Maria Cliborne at Rackheath.

Maria gave him at least three more children - George Thacker, born 1834, John Thacker, born 1837, and Ann Thacker, born 1841.

William Thacker died in 1874.

My G.G.G grandmother Susan Thacker, gave birth to my G.G grandfather, George Thacker in 1847 at Rackheath.  The father was not recorded.

George grew up to be an agricultural labourer and farm worker.  He married my ancestor Sarah Anne Elizabeth Daines (Photo above) in 1870.  Sarah (one of my mtDNA line) gave birth to at least ten children: George Thacker 1871, Ellen Thacker 1878, William Thacker 1876, my great grandmother Caroline Drusilla Thacker 1878, Catherine Thacker 1880, Thomas Thacker 1883, Rubin Thacker 1885, Walter Thacker 1887, Herbert Thacker 1891, and Rose Thacker 1893.

There is a family story about Sarah's strict paternal behaviour.  She was known as "Thacker by name, thacker by Nature" referring to "thacking" - to hit or punch hard.

My mt-DNA great grandmother Caroline married my great grandfather Samuel John Tammas-Tovell.

Exploring Gedmatch Eurogenes

The above grave is of my great great grandparents Robert and Ann Smith at Attleborough, Norfolk.

L1b Y-DNA News

First of all, it's looking good on the Y-Front.  My Y111 sample kit has arrived from FTDNA.  I also sent my 23andme V4 raw data to the administrator of the FTDNA Y Haplogroup.  He replied the next day "the raw data confirms that you are positive for M317 and negative for downstream SNPs M349 and M274. A very rare result for a NW European. It will be interesting to see who are your closest matches at 67 and 111 markers.".

So it doesn't look as though my L1b has anything to do with the M349 Rhine-Danube cluster.  I wonder where it comes from, how and when it got into an English ancestry?  It's starting to dawn on me just how rare it is in NW Europe.  European Y-Haplogroup maps and tables simply don't display or list it, because Y-DNA Hg L is not even considered a European Haplogroup, nevermind on British Haplo-maps.  All of those R1b's and I2's.  Not an L in sight.  I can see that having an unusual haplogroup is a mixed blessing.  Sure it's interesting, but no one knows much about it, because there is so little data on it in Europe, and so little research.

I had my first case of disbelief of my L1b Y-DNA on an FTDNA surname project group.  I reported my Y haplogroup as reported by 23andme (using ISOGG 2009) as L2*  The administrator retorted "It is NOT the "L" haplogroup, instead, it is "I".  So I linked her  copy of my 23andMe Paternal line report.  This time she replied  "Goodness gracious Paul. I administer many, many projects and yours is the first "L" You see, it has problems.

Wouldn't it be just great if I found someone else descended from the Berkshire Brookers by their Y line, that had the same haplogroup?

Gedmatch Eurogene admixture results for an Englishman

GEDMATCH offers free tools for analysing the autosome DNA of your raw data, from 23andme or Ancestry.com.  One suite of tools that are useful for analysing population admixture, are the Eurogene.  As an English person, with strong paper English ancestry - including almost certainly early medieval admixture, I thought that I'd get a comparison out of the way.  See which "works" best for my known ancestry and likely heritage.  I'm trying oracles on my 23andMe V4 raw data, for 1. EU Test, 2. K13,and 3. V2 K15.

A bit strange that it sees me as first "Cornish".  I don't know where it got that reference from.  I have no known Cornish ancestry.  However, 2 and 3 are likely.  As a whole it's not a bad prediction, just that the ball landed a bit to the West.
What about mixed populations?  What are it's favourite admixtures between two populations for me?

1   83.7% English  +  16.3% French_Basque  @  3.11
2   79% English  +  21% ES  @  3.17
3   63.7% English  +  36.3% FR  @  3.18
4   80.2% English  +  19.8% PT  @  3.5
5   51.8% FR  +  48.2% Scottish  @  3.54

Okay, not bad - it's given up on the Cornish.  However, it seems to point to France, Spain, and Portugal as a secondary source.  That is eerie, because 23andme threw up a speculative 2.4% South European including 0.5% Iberian.  I do wonder if I actually do have some unrecorded South European ancestry, even Iberian.

I like K13.  The Dutch may be there in admixture, and I know that they do often share some common patterns with SE English.  So I can excuse it making it to position 1.  Then in second place, the ball scores a goal.  Yes, I am SE English.  Most of the other suggestions could represent ancient admixture.

How about two population proposals?

1   65.6% Southeast_English  +  34.4% French  @  2.03
2   84.9% Southeast_English  +  15.1% North_Italian  @  2.05

4   69.7% North_Dutch  +  30.3% Spanish_Valencia  @  2.08
5   87.5% Southeast_English  +  12.5% Tuscan  @  2.09

It's got the SE English spot on, but all of these Iberians again!  Is it trying to tell me something?

7 West_Scottish 6.84
8 French 6.85
9 North_German 6.89
10 Danish 7.26

Very good, except again, a bit skewed to SW England.  However, to be fair, I do have some slightly westward ancestors in the Oxfordshire area.  The rest is spot on.
What does it offer as a hybrid?

1   73.9% Southwest_English  +  26.1% French  @  1.27
2   71.8% North_Dutch  +  28.2% Spanish_Cantabria  @  1.3
3   89.7% Southwest_English  +  10.3% North_Italian  @  1.35
4   91.6% Southwest_English  +  8.4% Tuscan  @  1.4
5   86.4% Southwest_English  +  13.6% Spanish_Galicia  @  1.43

Those Spanish again!  Goes for SW English over SE English as the primary ancestral population.

Out of these predictions, my gut feeling is that they are all good for single population match.  On two population mix, they all suggest Iberian minorities.  Either I have an undiscovered South European ancestor, or something else is going on.  Do other English get this?  I can't really pick a winner.


Our missing great grandparent

The above photograph is of my great grandfather, John Henry Brooker, with his partner Mabel Tanner.  Taken at Sheerness, Kent, in 1933.

The previous article was pretty much about this guy's ancestry, but I had to scan and post this photograph of him, to complete the story.  His father Henry Brooker, age 17, was still living with his father and two sisters in the village of Harpsden, Oxfordshire, in 1881.  By 1883 though, he had moved into Victorian London, and then married Elizabeth Shawers in Fulham.  I guess that London served as a magnet to young people born into the villages nearby.  Henry exchanged his skills of working with horses on the land, with those of working with horses in the streets.  He became a carter or carman.  Perhaps the docks offered work to Henry.  He moved first towards Deptford in SE London.  It was there, that Elizabeth gave birth to my great grandfather John Henry Brooker in 1884.

After 1891, they moved out further east along the Thames.  They settled in Lewisham.  John Henry Brooker went to school in Lewisham.  He appears to have exhibited some sort of educational skills, because at age 16 in Lewisham, he was recorded as a pupil-teacher.

Maybe it was because the Woolwich Barracks were located so close, that young John was drawn to it.  

Sometime also around this time, our great grandmother, Faith Eliza Baxter, moved from rural Norfolk, down to London, to work in service - following her older sister Polly.

Faith and John met. Young soldier meets young house maid, house maid falls pregnant.  They married, back at Faith's home of East Dereham in Norfolk, in February 1906.  John H was recorded as a "gunner in the 65th battery, RFA".  Their daughter, Gladys Evelyn Brooker was born at Dereham, Norfolk in early 1906.  I interviewed my great aunt Gladys by telephone many years ago.  She told me that John was posted to Ireland.  I've since found that his battery were posted to the army barracks at Ballinrobe.  Gladys told me that Faith accompanied him with a young Gladys.  The story that she was told was that John turned violent.  Then one night, Faith struck her soldier husband while he slept, and fled back to her parents in Norfolk.  My grandfather, Reginald John Brooker was born at Dereham, Norfolk, in 1908.  

In 1911, Faith was living at Northall Green Farm near to Dereham in Norfolk - where her parents lived, but in another house on the farm, headed by a single 27 year old farm labourer called Robert Hayes!  He states his place of birth as being Lancashire.  Faith is listed on the census as age 26, and married.  Young Gladys, age 5, and her little brother, Reginald, are in the same house.  So is their baby sister Winifred Hayes Brooker.

Gladys told me that Faith left Reginald to be reared by his maternal grandparents, William and Harriet Baxter, at Northall Green Farm, Dereham, while she was brought up by her single mother Faith, who later moved to Norwich. 

Several years later, the Great War exploded across Europe. A medal card at the National Archives, confirms that John was dispatched in the first wave:

Gladys told me that he remained in the Army, until the end of the War.  Here is the thing.  I'm presently making more efforts to trace more service records.  There is the possibility that they were among many records that were destroyed years later, by bombing during World War II.  Gladys did tell me that there was at least one attempt at a marriage conciliation between John and Faith, after John's mother encouraged him to make an approach - but it never worked out.  John and Faith went on to lived separate lives.  I don't believe though, that they ever legally divorced.

Above photograph of Faith Brooker, nee Baxter.

John then disappears from our family history.  On the back of the top photograph, Someone has written "Us & family at Sheerness July 1933".  I understand that the lady in the photograph was his partner Mabel, who he lived with for many years.

On the 1939 Register, on the outbreak of WW II, John was living at 50 Corbylands Road, Chrislehurst & Sidcup, Kent.  He was working as a clerk, at H.M Civil Service (Post Office Engineering Department).  John was recorded as married.  Mabel is there with him.  She is recorded as Mabel Brooker but also as single, and her occupatuion was "unpaid domestic duties".

Then in Dereham, sometime during the late 1940's, my father, just a boy, sees a motor car pull up in the street outside the family home.  Few people that he knew could afford a car.  An old man left the car, and walked up to the front door.  My father ran to the door in order to greet the stranger.  My father, all of his life recounted it.  He opened the door, looked up at the old stranger, and instinctively asked "are you my grandfather" without ever seeing him before.

Following this visit, my late Aunt Margaret actually got to stay with john, at his home in Kent.  She told me that she met Mabel.  When people came to the house, she was asked not to mention that she was John's granddaughter.  It appears that they never married, and I expect that was because John never received a divorce from Faith.  However, they lived as a married couple, and wished to remain that way.

The last record that I have of John was 1966.  John died late 1966, at Christchurch, Hampshire.  Perhaps they moved to the south coast for their retirement.  His will left his worldly goods to Mabel Tanner, commonly known as Mabel Brooker.

UPDATE 13.03.2026.

Geminin AI tells me:

To trace John Henry’s path from the barracks of Ballinrobe to the end of the Great War, we have to look at the movement of the 65th Battery, 8th Brigade, Royal Field Artillery (RFA).

​As a Corporal (and likely later a Sergeant or Warrant Officer given his "Scholar" intellect), John Henry would have been at the heart of the most technologically demanding transition in military history.

1911–1914: The Final Days in Ireland

​After the 1911 Census, the 8th Brigade RFA remained in Ireland as part of the 5th Division, one of the "Old Contemptibles"—the elite, professional British Expeditionary Force (BEF).

  • The Training: He would have spent these years in intensive live-fire drills at the Kildare Curragh, mastering the 18-pounder quick-firing gun.
  • The Professional Soldier: By 1914, he was a seasoned "Twelve-Year Man." Unlike the millions of volunteers who joined later, John Henry was a highly trained specialist.

1914: The Baptism of Fire

​When war was declared in August 1914, the 65th Battery mobilized immediately. They sailed from Dublin to France, landing at Le Havre on August 16, 1914.

  • The Battle of Mons: John Henry likely saw action almost immediately. The 5th Division was crucial in the retreat from Mons.

  • The Battle of Le Cateau (August 26, 1914): This is a defining moment for any RFA man. The 5th Division's artillery stood their ground against overwhelming German forces to allow the infantry to escape. It was a "gunners' war," and the losses were heavy.

1915–1917: The Western Front Grind

​The 8th Brigade RFA fought in nearly every major sector of the Western Front:

  • The Second Battle of Ypres (1915): Surviving the first gas attacks.
  • The Somme (1916): Providing the massive creeping barrages that required the exact mathematical "clerical" precision John Henry was known for.

  • The Italian Interlude (Late 1917): In November 1917, the 5th Division was sent to the Italian Front (near the River Piave) to bolster the Italians after their defeat at Caporetto.

1918: The Final Push and the Admiralty Transition

​By 1918, the Division was recalled to France to help stop the German Spring Offensive.

  • The "Scholar" Emerges: By this stage of the war, senior NCOs with clerical and administrative skills were often moved into "Battery Office" roles or logistical coordination. This is likely when he solidified the skills that would later land him his Admiralty Clerk position.
  • The Survival: Having served from August 1914 through 1918, John Henry would have been entitled to the 1914 Star (the "Mons Star"), the British War Medal, and the Victory Medal.

The Toll on the Man

​The "Proper Englishman" who visited your father in the 1950s was a man who had seen the absolute worst of the 20th century.

  • The Silence: Many RFA men suffered from hearing loss (due to the constant boom of the 18-pounders) and "shell shock." His quiet, disciplined demeanor in later life may have been a way of managing the trauma of four years of constant bombardment.
  • The Break from Faith: The war effectively ended his marriage. While he was in the mud of France or the mountains of Italy, Faith was back in Norfolk, deeply embedded in her own "informal" life. The war provided the clean break he needed to move to Kent and begin his "second life" with Mabel.

The Legacy of the "Gunner"

​When he handed over that silver watch, it wasn't just a grandfatherly gift. It was the watch of a man who had timed barrages at the Somme and checked his pocket for the hour of the "Big Push." It represented the precision that kept him
