Link to STR data for Southern English L M20 (Brooker / Chandler)

My Family Tree DNA Y111 STR test results are in.  Only yesterday, I predicted that ftDNA kit number 29369 could be of particular interest.  That prediction has now been proven correct.  Here is what I have learned since yesterday.

The 12 marker STR kit belonged to a descendant of a Thomas Chandler, that lived 1728 to 1782 at Basingstoke, Hampshire.  Although only 12 markers - it proved a perfect match for my first 12.  100%.  Family Tree DNA rated it's genetic distance as zero.

Basingstoke, Hampshire by modern road is only 32 miles (51 km) from Long Wittenham, Berkshire (now Oxon), where my surname ancestor, John Brooker lived, at the same time.  Based on the limitation of a 12 marker comparison, FTDNA give 71% confidence to the testers sharing a common Y ancestor within 12 generations, and 91% confidence of us sharing a common Y ancestor within 24 generations.  I'd say that suggests that myself and the present day descendant of Thomas Chandler, shared a common Y ancestral lineage until between circa 1500 and 1700.

So most likely, between the 16th and 17th centuries inclusive, the Y chromosome moved between two surnames, what we call an NPE (non parental event).  Usually either illegitimacy, where the Y-DNA detached from the surname of the biological father, or simply, the biological father of an ancestor, was not the husband of their mother.  This event most probably occurred in England, somewhere in the Hampshire, Berkshire, Oxfordshire area.  Both my Brooker lineage record, and the Chandler record, merge somewhere in that area.

It gets better.  Searches on FT-DNA, ySearch, and an email trail, revealed more Chandler Y cousins with an L haplogroup. All together, I have today found two 12 marker STR tests, that match my first 12 markers perfectly, with a prediction of zero genetic distance.  I have found another 12 marker with  slight difference, and a genetic distance of 1.  I have found a 37 marker test with some differences, but that still gives a genetic distance of 3.  A comparison with the Y37 test result, predicts 78% confidence of sharing a most recent common ancestor with me within 12 generations, and a 99% confidence of us sharing common Y descent within 24 generations.  This correlates quite nicely with the two perfect 12 marker testers.  All four testers are descended on the paternal line from Chandlers in the Basingstoke area.

Origins of the Chandler-Brooker L1b Y haplogroup

Family Tree DNA (ftDNA) is a commercial genetics genealogy company, with a reputation for cornering the market in Y-DNA testing, and in accumulating references for haplogroups.

That map above, that is the sum total of Y haplogroup L submissions on their database for the UK.  All four of them.  The two to the east are L2 and L2a.  The one in Oxfordshire represents my own pending results (expected L1b or L-M317).  Just to the south of that, the SW representative, is kit number 26369.

The cluster in Central Europe, is the "Rhine Danube Cluster", but that is L1a (L M349).

So you see, except for kit 26369, my Y haplogroup is way out here, like a distant satellite on it's own.  So what is Kit 26379?  Well, it is only a Y12 STR test result.  Predicted to M20, but it has been assigned to L-M317 un-clustered.  Up to now!  It's located only 32 miles south of my surname line during the 1740's.  Could it relate to our line?

 The above map of East Anglia, plots the ancestral events from my Gramps genealogical database, for my mother's ancestry alone.  All 100% of the events in her family history occur in East Anglia, with a significant concentration on the loam soils of East Norfolk, north of the River Yare, and shouldering up to the marshes of the Halvergate Triangle.  It includes events for the immediate families of 127 direct ancestors, stretching back to the 1680's in places.  Events include such things as births, baptisms, marriages, burials, deaths, census records, occupations, residence, etc.

Surnames include: Tovell, Tovil, Tammas, Tovell-Tammis, Lawn, Gorll, Gaul, Rowland, Dawes, Curtis, Key, Goffen, Goffin, Waters, Merrison, Morrison, Smith, Dove, Porter, Springall, Thacker, Daynes, Daines, Quantrill, Wymer, Rix, Hagon, Page, Nichols, Nicholes, Shepherd, Ransby, Briggs, Barker, Rose, Brooks, Larke, Dingle, Annison, Britiff, Symonds, Sales, Jacobs, Yallop, Moll, Hewitt, Osborne, Ginby, Ling, Briting, Hardyman, Hardiment, and Norton.  Surnames are all English or of Anglo-Danish origin.

Recorded religions are: Anglican Church of England, Baptist, Congregationalist (Presbyterian), Methodist, and Weslyan Methodist.  No Roman Catholicism, Islam, or Judaism.

The area has no significant immigration events in recent centuries, however, it has long held connections with the Dutch.  It is not near to the drained Fens (to the West of East Anglia), so would not have attracted any significant immigrant labour.  The City of Norwich has had communities of strangers, including medieval Jews, and more substantially, protestant refugees during the 16th century, from the Netherlands.   French Huguenots followed to Norwich.

The best known immigration to East Anglia, took place during the 4th to 11th centuries AD, from across the North Sea.  The elites of the Anglo-Saxon kingdom, claimed descent from the Angles, from Angeln  in the Schleswig-Holstein region of Northern Germany, that borders Denmark.  The area is rich in Anglo-Danish place-names.  East Anglia fell deep into the Dane-law.

Generation 2 has 2 individuals. (100.00%)

Generation 3 has 4 individuals. (100.00%)

Generation 4 has 8 individuals. (100.00%)

Generation 5 has 15 individuals. (93.75%)

Generation 6 has 30 individuals. (93.75%)

Generation 7 has 28 individuals. (43.75%)

Generation 8 has 26 individuals. (21.88%)

Generation 9 has 10 individuals. (4.69%)

Generation 10 has 4 individuals. (0.78%)

Total direct ancestors in generations 2 to 10 is 127.

The above photograph is of the wedding of my mother's parents, at Limpenhoe, Norfolk, in 1932.  It includes four of my great grandparents, and a great great grandmother.

I like to present my mother's heritage as a good reference for an area of particular interest.  An area that saw substantial early medieval immigration and admixture, from across the North Sea.  23andMe reports our haplogroup as H6a1.  Uploading the raw data to James Lick's mthap analyser, and to WeGene, both give a best match of H6a1a8.

That so much of her recorded ancestry, is so deeply rooted into East Anglia over the past 330 years, and particularly that one part of Norfolk, would suggest that she has strong East Anglian ancestry stretching back at least to the early medieval, and perhaps earlier.  I have recorded marriage between third, and second cousins, within her East Norfolk direct ancestry.  

Recorded Ancestry for Paul Brooker

Up to the 10th May 2016

This is just a little pat on the back, for what I have so far achieved in researching and documenting my known ancestry.  I really do like these Gramps open source software fan charts.  The names go off a bit, but the concept of a fan chart for illustrating the pedigree of direct ancestry, still works well.  It quite well displays the missing gaps.  Generations 1 to 5 (from myself, up to my great great grandparents) are complete.  The first few cracks appear from cases of illegitimacy at Generation 6, where the fathers were not named.  Generation 7 is still pretty impressive, with 77% of my great great great great grandparents named.  But it then starts to fall. back, with only 10% named for Generation 10.  I suspect that this isn't far off most genealogies that have been based on paper records.  Actually I'm quite proud of what i have achieved.

Through perseverance, I have recently extended both my surname lineage, and my maternal lineage to Generation 9 (early 18th Century).  They should in theory, align with my Y-DNA and mtDNA haplogroups respectively. 

The database for the entire family (including that of my ex-wife's) is now up to 1,546 individuals, with 195 direct ancestors for myself, as represented by this fan chart.

And yeah yeah yeah, I know, yours goes back to Ann Boleyn, Edward Longshanks, and Ragnor Lothbrok.  Well, I've not yet found one iota of heraldric blood.  I know that it will be there.  I know that I belong to a pretty homogeneous population, and that go back far enough, we English are probably all related to each other and to these people.  Go back even further, we could state that for all people.  Back to the MRCA's.  But I actually don't care.  I'm proud to be descended from hard working people.  It is they that I am making a record for.  They were equally valuable to any aristocrat or land thief.

I'm writing this post in response to a number of comments that I see online with regards to using a commercial DNA test, in order to ascertain ancestry.  Quite often, when someone asks how to find out their family history or ancestry, someone will come back with an answer in the form of "just spit in a vial, send it to Ancestry.com, and they'll tell you".  It's not really that simple, so I'm making this post, to explain how an ancestry DNA test can help, or not help, you discover your ancestry.  Nicely dumbed down I hope, for the beginner.

Traditional Genealogy

Traditional genealogists usually set out to create a genealogy (family history and tree), using interview techniques, artefacts, and oral memories, recorded from older relatives.  Artefacts might for example, include old family medals, or photographs.  They then extend the research, through documentary evidences, such as birth, death, and marriage certificates, church registers, census records, transcripts, electoral rolls, and military records. If they are interested in recording all ancestral information, and not merely a single line such as the surname line, then this research can go on for months, years, even decades.

What you cannot do, is to simply pay a small fee, and your entire family history drops through the letter box in a brown envelope.  It takes years of time to research, collate, and to verify a good family tree.  Most genealogy enthusiasts don't mind this, because they actually enjoy doing the research itself.  It becomes a hobby, even sometimes a passion.

However, a number of commercial DNA companies may give the general public the impression, that you now can simply pay a fee, spit or swab, and your ancestry magically appears for you on a website.  It's big business.  Does it work though?  Exactly what is genetic genealogy?

What is Ancestry and why do we care.

Ancestry can simply be defined as our descent from forbearers.  Why do we care who they were? Which forbearers or ancestors?  How many are there?  How far back?

Of course, not every one does care.  Not everyone cares about history.  But for other's how we define ourselves, our communities, and families, it does matter.  It tells us who we are, where we came from.  It defines us, gives us grounding.  It gives us identity.  Wars have often been inspired by ancestry.  At the same time, a deeper appreciation of the human family, and it's common ancestry, can be used to relate to those elsewhere.  One big family.  Discovering the immense poverty and hardships of our ancestors can help us to appreciate what we have, and to help others in need today.

So what ancestry can we discover?  For those few that merely concentrate on one patriarchal line, it's quite simple to define - the generations of a surname.  However, beyond that one narrow line of descent, few appreciate exactly how much total ancestry that we have.  Lets look at our biological ancestors at each generation:

• 2 parents
• 4 grandparents
• 8 great grandparents
• 16 great grandparents
• 32 g.g grandparents
• 64 g.g.g.grandparents
• 128 g.g.g.g grandprents
• 256 g.g.g.g.g grandparents.

These are only your 510 most recent direct ancestors, yet just those generations, will take you back to only around 250 years of family history.  Now add all of the recorded children of these direct ancestors - the great great uncles and aunts to the theoretical family tree.  You're probable going to have a tree of around 1,300 individuals.  That is just for 250 years.  You have a big family  Go back a few more generations, and it will explode before you reach far.  All of those direct ancestors though, are a part of your ancestry.  You'll most likely carry some DNA from most of them.  They are, from a biological perspective, who you are.

By the way, the number of biological ancestors will not continue to increase infinitely.  Because increasingly, you will find couples within your tree that are distant biological cousins of each other.  As this accelerates through thousands of years, that explains how all modern people around the world, all descend from a very small population around 100,000 years ago.

So before considering what DNA can do for genealogy, we need to consider which ancestors matter to us.  Do you just want to know who your biological parents, or grandparents were?  Do you want to know the names, places and social positions of your ancestors over centuries?  Do you want to know which parts of the world that your ancestors lived 500 years ago?  Do you want to know how some of your prehistoric ancestors moved across the globe, thousands of years ago?  Maybe you want to know everything.

Let's now turn to genetics for genealogy, and how DNA tests can answer some of these questions.

There are two main types of DNA tests for ancestry, although they are often incorporated together by commercial companies:

1. The haplogroups, the Y-DNA and mt-DNA
2. Autosomal DNA

The haplogroups are chains, or markers, that are carried on one of only two strict lines of descent.  They do not apply to your entire ancestry - just two lines.  As we saw above, we have 256 g.g.g.g.g grandparents (unless any of their descendants reproduced together).  Our haplogroups came from only two of them.  Your haplogroup does not define you.  Yet, it's quite odd, because very quickly, many genetic genealogists do relate to them, rather like a hereditary football club.  They do become an identity, only if you enthuse over them.

The Y or paternal haplogroup, follows the strict paternal line.  From father to son.  Women do not have a Y chromosome, so cannot pass it on.  It has to come from the biological father.  However, within this constraint, Y-DNA is particularly useful to genealogists.  It mutates often, both as STRs and less often, as SNPs (snips).  Because of these frequent mutations, it is useful for tracing shared descent with others.  It can also be aligned with surname studies.  The champion commercial DNA company for Y-DNA research, is Family Tree DNA.

The mt or mitochondrial (maternal) haplogroup, follows the strict maternal line.  From mother to children.  Both sons and daughter inherit their mt-DNA haplogroup from their biological mother.  However, only the daughters can pass it down.  Two downfalls to mt-DNA for genealogy.  1) The surname frequently changes, traditionally nearly every generation through marriage. 2) it doesn't mutate as frequently as the STRs of Y-DNA. It is still a useful tool, and can prove descent through the maternal line.  It can also still be used for studies of much deeper, ancient ancestry.

This is the bulk of you DNA.  All of the snips (SNPs), that make up who you are genetically.  You receive approximately 50% from each parent, 25% from each grandparent, 12.5% from each great grandparent.  This subdivision cannot go on forever, and indeed, once you go back much more than six generations, the approximates start to deviate, so that you may have no snips at all from a particular line that joined your family tree over 250 years ago.

The problem with autosomal DNA is that it can be such a mess.  It recombines randomly with every generation.  Therefore, it is much harder to track ancestry in the same way, that we can with the haplogroups.

So how can they be applied for genealogy:

Not everyone knows who their biological parents were, or where they came from.  This is the first use of DNA testing.  It can be used to find, test, or prove recent descent.  The first hurdle of genealogy.  Both haplogroup evidence, and autosomal evidence can be used to prove or determine relationship.

Cousins

Many genetic genealogists, use DNA to find distant, and sometimes not so distant cousins.  The hope is that they can link trees, share knowledge and research, perhaps copies of artefacts.  Therefore an awful lot of genetic genealogy is about tracing genetic relatives, and establishing common ancestry.

There are two main tools:

• Haplogroup Projects.  The Y haplogroup is favoured for it's frequent STRs, and also for it's link to surnames.  Family Tree DNA projects track the STR and SNP data of it's members, tracking families, relationship, known mutations.  Project administrators at FTDNA can predict relationship to other members in the project.  Your Y cousins.
• Shared segments.  Autosomal DNA can be used for finding distant cousins.  23andMe for example, have Relative Finder.  Alternatively customers of any commercial DNA company that gives them access to their raw data, can upload that data to GEDMATCH.  At GEDmatch, they can search for other kits, looking for lengths of shared segments (measured in cM - centimorgans) on the autosomes or X chromosomes.  The longer or more segments can be used to indicate shared ancestry.

It is important to understand, that this is not about directly tracing ancestry.  It is only about establishing shared biological ancestry, with other researchers, with which you may be able to share resources.  In the old days of genealogy, we would find distantly related researchers by browsing through annually printed surname interest directories.  Here, the same thing is happening, but we are finding people by comparing DNA.

Ancestry from Autosomes

Most commercial DNA companies providing ancestry information, now use their own propriety calculators to look at the autosomal DNA of their customers for patterns that they can relate to a number of reference populations.  23andMe for example, uses Ancestry Composition to determine what parts of the world, that the ancestors of their customers lived 500 years ago.  They predict from this in percentages of ancestry.

However, it is very much a developing art.  The problem is that genes have been randomly mixing and moving around ever since prehistory.  The customers of these DNA companies want hard facts.  They want their ancestry accurately pin pointed down to modern or ancient nation-states, or to historical populations such as the Vikings or Huns.  Ancestral DNA companies are under pressure to provide this deep ancestry.  However, can they?  Ancestral analysis of DNA can be very enlightening.  It can provide some surprises within a family history.  However, it's accuracy is exaggerated.  It is increasingly successful at predicting ancestry from a particular corner or end of a particular continent.  But it cannot for example, accurately tell French, British, and German ancestry apart to any high accuracy.  It can recognise some populations better than others.  It cannot tell anyone if they had Viking ancestry.

Ancient Ancestry

This is a particular value of the haplogroups.  As we accumulate more and more data on more mutations, as we expand the recorded database, and as we relate that to more ancient DNA extracted from referenced and dated ancient human remains, so we will be able to better explore the population genetics not only in history, but deep into prehistory.

However, it is also becoming increasingly realised, that patterns of ancient admixture can also be detected within the autosomes.  Although Autosomal DNA ancestry calculators claim to reveal relatively recent admixtures over the past 500 years, it is becoming clear that these are being confused by much older patterns of admixture.  These patterns can now be explored and probed on a number of GEDmatch programs.  People can compare their DNA with the kits from ancient DNA, or predict just how much of their ancestry was likely "Western Hunter-Gatherer, or "Early Neolithic Farmer".

In addition, more DNA companies are now measuring for much more ancient admixture with archaic populations such as the Neanderthals.

Conclusion

Genetic Genealogy is fun, great fun.  It is not however, a quick and easy replacement for traditional genealogy.  Unless you get lucky with some comparative Y-DNA in a project, it is not going to directly tell you the names or social status of any ancestors.  It can give you a phylogenetic tree, but not any kind of family tree that you can bore other family members with.

Genetic genealogy can provide some tools to some researchers.  It can test biological relationship.  It can be used to predict some of your ancient history.  For most researchers, particularly those that are able to interview many local family members, search local grave yards, access archives and records - it has no, or little value to the pursuit of collecting ancestors.

I personally love to explore my genetic genealogy. But it is documentary research that provides the names.  Genetic genealogy for myself, is more about the long and ancient journey.

I'm ready to accept the connection.  I've talked to people with more expertise than me concerning the confusion over the ages of my couple on the census.  I've found the baptism on a transcription CD for Long Wittenham from Oxfordshire FHS.  It's perfect.  The cream on the cake though, is that I found someone else with a tree on Ancestry.com, that had already come to the exactly same conclusion.  Okay, I don't normally take much notice of trees on Ancestry.com, but this one appeared well researched, and I've both checked and added to the details on that tree.  Third time lucky.

G.G.G.G.G.G. Grandparent Generation

I can now go back to an ancestor named John Brooker, there's a few of them, so let's call him John Brooker I.  He might have been born somewhere in the Thames Valley, during the early 1720's.  He married a Mary, my G.G.G.G.G.G Grandmother Brooker.  They settled (if they didn't originate there) at Long Wittenham in Berkshire, near to the River Thames.  She gave him at least six children between 1749 and 1763:  Mary, Anne, John, Edward, Martha, and Sarah.

G.G.G.G.G Grandparent Generation

Their son, Edward Brooker (or Brucker), was our ancestor.  He was baptised at Long Wittenham on the 16th January 1757.  When Edward was 29 years old, he married local girl Elisabeth Gregory, on 24th October 1786, at Long Wittenham.  So you see, that photo above of the church of St Mary's there, is a part of the story.  Our 18th Century Brooker ancestors were baptised, and sometimes married there.  Some of them are also buried in that church yard.  Indeed, that was where Edward himself later ended up, when he was buried there 23rd September 1832, having died at the age of 75 years.

His wife Elisabeth had also been born at Long Wittenham, the daughter of a William and Anne Gregory.  She had been baptised at the above church on 15th November 1761.

Edward and Elisabeth Brooker appear to have lived in Long Wittenham all of their life.  They had five children baptised at St Mary's between 1789 and 1796: John, Dinah, James, Richard, and Joseph.

G.G.G.G Grandparent Generation

Our ancestor John Brooker II was baptised on 18th January 1789.  At the age of 25 on 31st October 1814, John married Elisabeth Seymore at the nearby market-town of Abingdon-on-Thames, in Berkshire.  Elisabeth was born circa 1797 at a village north of the Thames in Oxfordshire, that in later life on a census, she referred to as Drayton.  Most likely, this is the village of Drayton St Leonard.  It's only a mile or two across the river from Long Wittenham.

I should at this point explain why I sometimes refer to long Wittenham as in Berkshire, and at other times a in Oxfordshire.  Historically, it is a Berkshire parish, and is on the south side of the Thames.  However, in 1974, it was transferred to Oxfordshire County Council.

The couple moved, and they moved around twelve miles.  That chucked my attempts to trace them for a long time.  They moved to Rotherfield Peppard in South Oxfordshire, down river.  They turned up there on the 1841 census.  They must have moved soon after marriage, as their children were born in Oxfordshire.  John was employed as a labourer, most likely a farm worker.  Between 1815 and 1836, they had seven children: Frederick, Phoebe, John, Elizabeth,Mattew,Emma, and William Brooker.  Later in life, they moved to the next village of Rotherfield Greys.  It was there on the 1861 census, that I finally picked up their origins.  John died in 1867.

G.G.G Grandparent Generation

Our ancestor, John Brooker III was baptised at Rotherfield Peppard on 23rd April 1820.  In the 1841 census, he turns up in a house of multiple adults on Hamstead Farm in the next parish of Sonning Common.  Although technically north of the Thames, and in Oxfordshire, it actually belonged to a parish south of the river in Berkshire.  John was an agricultural labourer.

On the 1st February 1845, at nearby Shiplake in Oxfordshire, John married Mary Ann Edney.  They lived at times in both the South Oxfordshire parishes of Shiplake, and of Harpsden, both close to the town of Henley-on-Thames.  Between 1847 and 1870, Mary gave birth to at least ten children: Hannah, Charles, Arbina, Phoebe, Emma, Thomas, William, Henry, Alice, and Ellen Brooker.

Mary Ann Brooker herself, was the daughter of Thomas Edney, a thatcher at Shiplake, and his wife Hannah (nee Hedges).

John lived to a good age.  During the 1901 census, he was living with his eldest daughter, Hannah Belcher and her husband.  He was 81 years old, and working as a shepherd.  John finally passed away in 1912, at the age of 91 years.

G.G Grandparent Generation

Our ancestor Henry Brooker was baptised at Harpsden on 5th December 1863.  An early appearance as a young man on the 1881 census, lists him as a farm worker, at Harpsden Bottom Cottages.

Henry had itchy feet though.  He wanted to move right down the river, into London.  A few years later, on the 29th September 1883, Henry married Elizabeth Rosina Shawers, at Fulham, London.  Elisabeth was born at Haggerstone, London on 11th September 1858.  her father, Henry Shawers was a harrow weaver, but her mother Elisabeth (nee Durran) also hailed from Oxfordshire.  I've traced her ancestors to the area around Woodstock and Deddington.From Fulham, the couple next moved to Bethnal Green, and then to Deptford.  I only know of two children, born between 1884 and 1887.  Perhaps something prevented Elisabeth from carrying again.  Their children were: John Henry Brooker, and Elisabeth Rosina Brooker.

They later moved down river yet again, to Lewisham.  Henry worked mainly as a carter, driving a horse and cart in the East End of Victorian London.  I've long suspected that he may have worked on the docks.  However, by 1908, he was recorded as a store keeper.

The above photograph is of our great grandfather's sister, Elisabeth Rosina Brooker.

I don't yet know when or where Henry passed away.  However, I do know that Elisabeth spent her last days living with her son at Sidcup, Kent.  She was buried there on 2nd May 1939.

Great Grandparent Generation

Our Ancestor John Henry Brooker was born 25th June 1884 at Deptford, London.  However, the rest of the story - still needs to be written, or has already been written in other posts.

The Y chromosome.

I have so far been tested to have the Y haplogroup L-M317, or L1b if you prefer.  It means nothing, except that is incredibly rare and enigmatic sub clade, particularly in NW Europe.  It may mean that at some point, my paternal line lived in Eastern Anatolia, south of the Causacus, or near to the Black Sea.  I'm waiting for further testing, but it looks quite possible, that it is linked to the Pontic-Greek ethnicity that lived in that area.  I have no autosomal evidence of anything from that part of the world, so it is likely to have been in England or NW Europe for quite some time.  It might for example, have arrived here via the Roman Empire.

Why mention that now?  Because until it meets an NPE (non parental event), it should follow the surname line.  If I ever met another Y chromosome descendent of my Thames Valley Brookers - another person that has descended directly through a strictly father-to-son paternal line, I'd love to know if they've had their Y haplogroup predicted.
