Most of our nuclear DNA recombines with every generation. But a yDNA Haplogroup is a genetic marker that follows along the direct paternal line, passed down from biological father to son. Follow it back, and it will follow your father's father's, father's, etc.  Most NW European males carry a yDNA haplogroup of R, or I. Sometimes G, J, E. However, I have a variant of L, defined by a mutation coded M20 (L-M20). yDNA haplogroup L is regarded as Non-European and some will insist that it is South Asian. I can reliably trace my own paternal line back to 18th Century Oxfordshire / Thames Valley.  yDNA haplogroup L is NOT seen as European. It is seen as an Asian genetic marker. The males of two English families share my own mutations: BROOKER of Oxfordshire and CHANDLER of Basingstoke, Hampshire. My next closest yDNA matches are men from Iran, Iraq, Saudi Arabia, Turkey, India, and Lebanon.

Genetic history of Cambridgeshire before and after the Black Death

Cherry Hinton 919 (sk3262) was related to a female (mother, or sister?) number 947 (sk3262) with whom he shared his mtDNA haplogroup U5b3e His yDNA was sequenced as L-B374.

Documentary Paternal line.

I have proven descent from John Henry Brooker, through genetic matching to support the documentary evidence. I and my sibling share some centimorgans of autosomal DNA with descendants of his sister. Additionally, smaller segments are shared from the prior few generations, to support that this paternal line is biologically true, at least back to Generation 5 (great great grandparent). He was the only one of my great grandfather's not to be Norfolk-born.

If I follow his paternal line (BROOKER) back using traditional genealogical method, I follow it back to the Thames Valley borderlands of rural Oxfordshire and Berkshire. I have good, strong documentary evidence back to my direct paternal line 5 x great grandfather, Edward Brucker, born 1757 at Long Wittenham, Berkshire.

Support for my 6 x great grandfather being a John Brooker born 1722 at Hagbourne, Berkshire in 1722 is pretty good. His father before him I have verified, was another John Brooker born 1691 at Hagbourne. His father was Thomas Brucker, also baptised at Hagbourne in 1658.  If biologically true, he would be my 8 x great grandfather and that would place my Y chromosome in Hagbourne, Berkshire in 1658. The Chandlers who share the yDNA descend from a Thomas Chandler who lived in Basingstoke, Hampshire during the late 18th century. At some point prior to that, our two paternal lines must merge.

Anything earlier than 1658 Hagbourne, too much doubt creeps in, but I have candidates stretching back a few generations waiting for more supportive evidence. They are in the Wantage/Uffington area of Oxfordshire. Caution - they may be incorrect. Another candidate in in Whitchurch, Hampshire.

I've researched the BROOKER surname:

Distribution of BROOKER baptisms AD 1550 - AD 1600 by English County.  County boundaries modern, but East and East Surrey united for historical purposes.  Includes records of derivations of Brooker surname.

During the 16th Century CE, it was not a common surname in Oxfordshire and Berkshire. Its origins are the Sussex / Surrey area. It is possible that I had a Brooker surname ancestor move up through Hampshire into the area. I think that our surname picked up the yDNA in Hampshire, or in a South English port. My favourite hypothesis is that a South West Asian sailor visited, and left a son there early into the Medieval.

This hypothesis might seem unlikely, yet it brings me to:

Within hours of publishing my most recent hypothesis: Was our ancestor a Baloch Lascar, I receive news of an incredible rare event.  Someone else on the FTDNA Big Y tested to Y Haplogroup L L-SK1414 (L1b2c).  The sample belonged to a Druze genetics project, and was taken from a man from the Druze town of Zaroun (Matn District) in Lebanon.  The project administrator told me "his ancestors -at least for the past 1000 years- should have been either residents in Mount Lebanon or migrated as many other Druze families from the Idlib region in NW Syria (Jabal el Summaq Mountain)".

The Druze

When they went further back in time, the researchers discovered another interesting finding. It came to light that, 500 years prior to the beginning of the Druze religion, around the 6th century AD and at the time of the birth of Islam, a genetic group began to take shape that formed the basis of the Druze community’s ancestors.

According to this study, the Druze genome is largely similar to the genome of other Arab populations in the Middle East. They also found a few genetic elements in the Druze genome that originated from Europe, Central and South Asia (the Iran region) and Africa.".

Source.

Studies have found that although a variety of both Y and mt haplogroups can be found in the Druze community, they appear to have been isolated for that time period.  So a haplotype found within the Druze, would have been in the region of North-West Syria and Lebanon, during the 11th Century AD.

How does this change my perspective on my Y origins into Europe?

L-SK1414 now looks more dispersed across Western Asia, from the Levant, to Pakistan.  That might mean that my medieval Y migrant from Asia to England didn't take a Lascar route from the Persian Gulf / Arabian Sea after all.  It could be that they traveled from the Levant along the Mediterranean, or even across Europe?  They may not have a Balochi connection - they could have been of many Asian ethnicities.  It's a good example of how easy it is to develop a hypothesis based on too little evidence.

As for the origins of L-SK1414, I'm now looking a little more south, and a little more central.  Favourite suggestion now is Tigris and Euphrates Valleys, and the Zagros Mountains, in Iraq and Iran.  L-SK1414 could have dispersed westwards to the Levant, and eastwards to Makran, SW Pakistan.

Here is the distribution of recorded Y haplotype L-SK1414 so far in Western Asia:

Note the centralised nature of the Iran / Iraq "Cradle of Civilisation" to L-SK1414.  Could our Y ancestors have passed through Ancient Mesopotamia?  Now there's an interesting thought!

I've created this distribution map of known Y haplogroup L, L1b2c or L-SK1414. This is my Y-DNA haplotype.  Not a lot of dots there are there?  This is how rare that this clade is.  L1a and L1b most likely (in my opinion) originated during the last Ice Age circa 18,000 years ago, south of the Caucasus, and west of the Caspian Sea in Western Asia.  In other words, in the area of present day Armenia, Azerbaijan, and North-west Iran.  Again, I emphasise, that is just my opinion, looking at present-time evidence.

Y haplogroup L itself may have diverged between L1 and L2, not so much earlier, or so far away from this region.  Again, just my present opinion.

My sub clade of L1b, is so rare, that it is impossible to say.  As can be seen from the map.  However, this is my blog, so I'm going to push out on this one.  My very best guess would be further to the East than it's parent.  I suspect South East of the Caspian Sea, in what is now Eastern Iran.  I could well be wrong.  We have so few tests from nearby Afghanistan for example.  So far, the SNP SK1414 has only been reported twice.  1) in Makran, SW Pakistan, in a Balochi speaking man.  Balochi is an Iranian language, closely related to North-West Iranian languages.  Researchers suggest that the Balochi people of Makran, largely migrated from south west of the Caspian.

The only other guy in the world so far confirmed is little old me, an Englishman.  I trace my surname (direct paternal) line back to the Thames Valley of Oxfordshire / Berkshire 270 years ago.  If my biological line follows that.  A number of STR testers of English descent appear connected to me by STR analysis.  They all descend from Thomas Chandler, who lived around the same time as my earliest recorded ancestor - only 32 miles away at Basingstoke.

From all of the evidence, I conclude that my Y ancestral line moved, probably in one generation, from Western Asia, perhaps from he edge of Persia, to Southern England conservatively between 2,000 and 400 years ago.  Although I would speculate between 1,600 and 600 years ago - during the Medieval or close by.

Bridges and Walls, Snakes and Ladders

I've noticed two perspectives within the broad scope of genealogy where it ties to population genetics.

• Some people, those with nationalistic, right wing political views, frequently look for what divides their ancestry from others.  What defines and ties them to a historical population, or even to a land.  They may well want to prove connection to a romanticised historical group within their part of the world.
• Others - those of a more international, liberal persuasion, instead tend to look for what unites them with other peoples alive today - what connects them within the community of humanity.

I have to confess to being more of the latter.

On Paper

I started out with a pretty well researched paper genealogical record.  A family tree.  A family history.  Researched through oral history, interviews, parish records, state records, and then on to digitalised records in more recent years.  A genealogical database of 1,570 individuals for my kids, and 207 direct ancestors recorded for myself - going back to the 1680s.  My recorded ancestry was 100% English - dominated by the County of Norfolk.  The majority of present day English perhaps have some non-English ancestry, perhaps Irish or Scottish, or something a little further afield.  I didn't find any.  All English surnames, and English denominations.  Some of those surnames however, did echo rather more ancient immigration from across the North Sea.

Autosomal DNA Testing

Autosomal DNA testing for ancestry provided a bit of a surprise.  I took a 23andMe DNA test, along with my mother, who's results I phased with to provide more accuracy.  The 23andMe Ancestry Composition analysis in standard mode didn't simply see me as English, or even as British.  It did see me pretty much as 100% European.  Not a hint of Africa nor Asia within the past several hundred years.  It saw 86% of my autosomal DNA as definitively North-West European.  However, it could only see a mere 17% as distinctly belonging to British & Irish.  So, the ancestry test of my autosomal DNA certainly agreed that I was European, NW European even, but couldn't be sure on how English or even British that I was.

23andMe Ancestry Composition in the very unreliable speculative mode rated my British/Irishness at only 37%.  The highest percentage of focus - but it saw 22% of my autosomal DNA ancestry as French / German, 1% as Scandinavian, and 2% as South European.  So considering my 100% English ancestry on paper, autosomal DNA testing couldn't really be very sure about my ancestry.  Even in speculative mode, it had 34% of my DNA as "Broadly NW European", meaning that it couldn't be sure, but somewhere in that corner of that continent.

Fair enough I suppose.  I've lost a certain amount of faith in any autosome DNA tests for ancestry to be able to pinpoint the English.  You see, even ignoring recent waves of immigration of Irish, Scottish, French, Germans, West Indians, South Asians, etc, etc.  The truth is that the English were already a very admixed population even 1,500 years before present.  Already a mixture of prehistoric populations, immigrants from across the Roman Empire, then from across the North Sea, from the Low Countries, Northern Germany, Denmark, Scandinavia, etc.  23andMe claim that their product reflects your ancestry 500 years ago.  No it does not.  It uses modern reference populations.  Genes have been circulating around the World for a long time.  Autosomal DNA tests for ancestry have really improved.  They are pretty good now for recognising a Continent - sometimes even a corner of a continent, as the source of some ancestry.  But they cannot pinpoint many populations with accuracy, and they cannot pinpoint the English.

So, my paper record said English.  My 23andMe autosome DNA test said North-West European, but couldn't even pinpoint British.  It suggested admixture.  It did however - this is important - only see me as European.  Okay, in Standard Mode, it did have a tiny 0.3% that it failed to assign to Europe, nor anywhere.  It did not see Asian.

Haplogroup DNA Testing

Haplogroups follow two narrow lines of ancestry.  The Y follows the direct paternal line, the MT follows the direct maternal.  They do not represent the bulk of your ancestry.  However, they can tell a more accurate, and longer term story.  Ancestry can be lost in Autosomal DNA within a few centuries.  In addition, it gets messed up through recombination.  Not so with the two haplogroups.  So where did mine come from?

My MT-DNA

There is an awful lot that we will know in future about our haplogroups, that we don't yet know - especially in the case of mt-DNA. However, we do know that my haplogroup, H6a1, did not originate in Europe.

H is common in Europe, and it most likely originated either there, or in South West Asia, during the Upper Palaeolithic. H6 did not originate in Europe.  It may be West or Central Asian in origin.  H6a1 has not been recovered in any ancient DNA within Western Europe.  However, it has been recovered in the DNA of the Yamnaya on the Eurasian Steppes.  For this reason, it is generally thought - based on evidence so far, to have been brought into Western Europe during the Early Bronze Age, by the expansion from the Eurasian Steppes at that time.

It isn't too fanciful - based on this evidence, to imagine that my distant grandmothers belonged to tribes of Early Bronze Age pastoralists, living on the Steppes of what is now the Ukraine.

My Y-DNA

This one has been a cracker for me.  Anyone that has followed my blog, might be getting bored with this.  I've thoroughly tested my Y-DNA.  It's not an exaggeration to suggest that it is quite likely Ancient Persian.  Based on current evidence, I believe that my Y-DNA arrived into England within the last millennia - probably between 350 and 800 years ago.  I'm still working on it's most likely route here.  I do believe that it was most likely still located in the region of Iran circa 1,000 to 2,000 years ago.  My nearest 111 STR match is to a guy in Australia who's paternal line lived in Birjand, Eastern Iran.  We shared a common ancestor around 2,000 years ago.  My terminal SNP is shared on record with only one other man so far - in the world.  He was a Balochi speaker that lives in Makran, SW Pakistan - close to the border with Iran.  The Balochi are believed to have migrated from North Iran between the 5th and 14th centuries AD.

A bit more distant, I have a Y cousin in the USA that maybe I shared a common ancestor with 3,000 years ago.  He is of Azores Portuguese descent on his Y line, but he carries a distinct STR marker that has been associated with the Parsi, who migrated to India and Pakistan, but originated in Iran.

And going further back, the Y haplogroup L most likely originated within the area of Iran and Iraq, during the Ice Age.  It would have been carried by Upper Paleolithic hunter-gatherers in that region.  13,000 years, I shared grandfathers with two Pontic Greek Y cousins, who's ancestors lived in Trazbon, Eastern Anatolia.  Maybe one Y ancestral son headed to the Black Sea, the other settled at the Caspian Sea?  The Ice Age was drawing to a close, but with a ferocity and climate instability that drove bands of people apart and into refuges at that time.

The Parsi connection keeps hinting.  They descend from Persians that worshiped the ancient religion of Zoroastrianism.  I've just seen a Y haplogroup study of men in Pakistan.  The background level of Y haplogroup L-M317 sat at 1.1%.  However, in the sample of Parsi men there - it spikes up to 13.3%.  That might not be the route however, of my Y line.  The SK1414 SNP turned up in that same study, but that was found on the Makrani Boluch man that was tested L-M317, not in the 12 Parsi men that also tested positive for L-M317.

Conclusion

I prefer bridges to walls, and that is what I got.  My paper ancestry said 100% English - much of it East Anglian.  I'm quite proud of that, but I'm equally proud of my more distant ancestors that emigrated here.  I've found North Sea admixture, from places such as the Netherlands and southern Scandinavia.  I've found a grandmother in a Bronze Age tribe of pastoralists in the Ukraine.  I've found ancient Persians, descending from hunters of Ibex in the Iran / Iraq region.  I've found distant cousins in the USA, Iran, Pakistan, Australia, and Turkey.

One species, one family.

The Parish Church of All Saints, in the South Oxfordshire village of Rotherfield Peppard.  Taken on my phone cam during a recent ancestor hunt in this area.  Rotherfield Peppard is the location of my earliest verified Brooker ancestors.

Background

Many years ago, perhaps nearly twenty years ago, I had traced my surname family line to a John & Elizabeth Brooker that lived in the South Oxfordshire village of Rotherfield Peppard during the 1841 census.  My trail came to a dead end with that John Brooker.  He was my G.G.G.G grandfather, and was born circa 1787.  John fathered another John, who fathered Henry, who fathered John Henry, who fathered Reginald John, who fathered my father.  My surname trail has been stuck there ever since.

Until perhaps very soon into the future.  I lost interest in genealogy around twelve years ago or so.  Really, my interest started to drift away perhaps soon after discovering the above dead end on my surname line.  Then an impulse buy of a 23andMe kit this January, and inspired by the new genetics side of the interest, I returned to genealogy a few months ago.  I discovered the advantages (and some of the downfalls) of 21st Century Internet Genealogy.  I've expanded my family tree in several directions using these new resources.  But that old surname, that continued to frustrate.

You see that 1841 census, it left me with a teaser.  Later censuses record the actual parish of birth, and actual age of each person in England & Wales.  The 1841 census however, merely asked people if they were born within the county of residence or not, and summarised their ages into five year round ups.  Elizabeth stated that yes, she was born in Oxfordshire.  John on the other hand said No!  He was born outside of Oxfordshire.  I remember the long drive home from the Oxfordshire County Record Office many years ago, and considering that answer.  I knew that the nearest other county was Berkshire, and that I kept seeing Brooker families in Berkshire.  I speculated that he most likely was from Berkshire.  It was a bit of a surprise, because my wife at that time, and the mother of my children had ancestors herself nearby in Berkshire.

The Y Factor

That 23andMe DNA test revealed a number of surprises.  One of them was that I had an incredibly rare Y-DNA haplogroup for North-West Europe.  As a Y haplogroup, "L" is mainly found in any percentages in South Asia, particularly in South India, and also around Pakistan.  My actual sub clade however, is rarer, and is mainly found south of the Caucasus in Western Asia, where Anatolia meets the Levant.  One ethnicity that it has been linked to are the Pontic Greeks that traditionally lived around the Black Sea.  I'm presently investigating it with a thorough ftDNA Y111 STR test, followed by an ftDNA Big Y test.  Yes, I've chucked too much money at it.

Okay, it's just a genetic signal, just a marker.  It doesn't have any value nor effect on who I am.  But it does link me to a part of the World in a kind of personal, measured way, that I never imagined.  I do want to know, so far as I can, how this Y haplogroup got into Europe, into North-West Europe, into Britain, and into my Brooker surname line.  Can I use it to link to any distant Y cousins, that live today or perhaps in the past (ancient DNA) in other ethnicities?  Will any Brookers directly descended from the same Oxfordshire cluster of Brookers, ever test, and record their haplogroup online?  If I don't test and record myself, then no, that will never happen.  I'm not expecting recent cousins.  I hope to merely find very distant cousins.  In a sense I already have.  I have many in India, Pakistan, Armenia, Syria, Chechnya, etc.  We all do.  However I know have a link that I can measure.

This has forced me to re-launch my investigation in my surname line.  Will I find any clues to how and when it entered the line?

"There aren't many Brookers around here"...

It should be easy right?  Even local genealogists have said to me "there aren't many Brookers around here".  Wrong. There are a lot in the Thames Valley, and they've been there quite some time.  Most researchers of the Brooker surname, end up in Kent/Sussex.  That is because Kent is the English county, with the highest density of the Brooker surname today in telephone directories etc.  At first, I thought that my Brooker line came out of Kent, because my great grandfather lived at Sidcup for many years.  However, I later discovered that his father actually originated in South Oxfordshire.  There are scatters of Brookers across England.  There's even one family established in Suffolk.  The Oxfordshire / Berkshire Brooker cluster however, is second only to the Kent/Sussex cluster.  They've been in the Thames Valley quite some time.

So, on returning to genealogy, I start to use the new Internet resources.  FamilySearch.org, Ancestry.co.uk, FindMyPast.com.  I search for John Brooker born circa 1787 anywhere, but particularly in Berkshire.  I narrowed it down to about three candidates, and then by a process of elimination down to one, my most likely candidate.  I check censuses to see if John Brooker of Berkshire disappears before my validated John Brooker of Oxfordshire emerges on the 1841 census, married to Elizabeth, with several kids.  Finally, I settled on my favourite.  He was born at Hurley, Berkshire.  Only four miles away from a major bridge over the Thames into Henley, Oxfordshire, and seven miles from Rotherfield Peppard.  I even travelled down to the area, to check it out.  It was all so plausible.  I'd cracked the puzzle after all of these years.  Noone else on Ancestry.com sharing my Brookers had come up with the same answer.  Most were stuck at 1841, or later.  One had a silly proposal to a highly improbable ancestor.  I had reached Hurley.

In Hurley, I took this new extension back to another John Brooker, before him a Richard Brooker, before that another Richard Brooker, as well as some of the maternal lines.  A cracking breakthrough.  I was back to G.G.G.G.G.G.G grandparents on my surname line.  I was chuffed, even announced it here and on Facebook.  Hurley was the ancient home of the Brookers.

And what a beautiful village!  The church at Hurley above.

But it was incorrect.  A nagging feeling that I really had not searched thoroughly enough, that this John Brooker of Hurley, totally disappeared before mine appeared in Rotherfield Peppard.  I want all of my genealogy to be well validated and properly sourced.  But particularly for my surname line.  I'm spending a lot of money on those Y chromosome tests.  I don't want to tag it to a bad, untrue ancestry.

So I took another look.  I found a doppelganger in the Hurley area.  He had children there, in the parish next to Hurley.  He fit the John Brooker born in Hurley during 1789 even better than my ancestor.  I had rushed, messed up.  I was too quick to accept the link.  I made another mistake.  It meant deleting a whole bunch of ancestors from my family tree.  But it had to be done.

So many Johns and Elizabeths

I kept looking online.  I kept seeing other John Brookers.  I even kept seeing more John and Elizabeth Brooker families!  Everything that I checked out on Ancestry.com and FindMyPast.com fails tests.  I need good evidence.  It was the free LDS service at FamilySearch.org though that provided the next candidate.  I see references to a number of children born to a John and Elizabeth Brooker at Sonning, Berkshire.  The children were all slightly older, and had different names to any of those later at Rotherfield.  I looked up Sonning.  Sonning Common was actually north of the Thames, right next to Rotherfield Peppard!  I even discover that my G.G.G grandfather John Brooker (Junior) was living there in 1841!  Eureka (again)!

I'm recording everything now.  I even buy some marriage and death certificates from the GRO, looking for any link whatsoever.  Any correlation.  Any new note or mention.  I also start to purchase CD-ROMS of transcripts of parish registers from the Oxfordshire FHS, and to consult them by email.  When I look closer, I can see that if this family really were mine, then the mother, Elizabeth, must have been incredibly young at marriage, around sixteen.  I'm starting to have doubts again.  A researcher from Oxfordshire FHS replied.  They explain the confusing situation with Sonning Common.  It belonged to a parish south of the river, in Berkshire.  They also doubted the connection.  The births just didn't fit.  My CD-ROMS start to arrive.  They didn't fit.

I'd chased the wrong connection again, for a second time.

If you don't succeed at first...

The latest attempts.  I'm not giving up yet.  Hurley was wrong.  Sonning was wrong.  I can still get this.  Then the other night, I played with some more online searches, and I see something on the 1861 census of Rotherfield Greys, that I hadn't spotted before!  There was an old couple living in another neighbouring parish by the name of John and Elizabeth Brooker.  Not only that, but the 1861 census recorded their parishes of birth.  This John Brooker was born at Long Wittenham, Berkshire.  Elizabeth was born at Drayton, Oxfordshire.  It fits.  Elizabeth Brooker born inside Oxfordshire, her husband John born outside of Oxfordshire!  And so close!  Have I done it this time?

There is a problem with the connection.  The ages are wrong.  According to the 1841 census, my ancestor John was born between 1787 and 1791.  The 1861 John was born 1781 - according to the enumerator.  Equally, in 1841 Elizabeth was recorded as being born between 1797 and 1801.  This 1861 Elizabeth was recorded as being born 1786.  They're too old.

However...  a search for a John Brooker baptised at Long Wittenham, produced two transcripts of a John, son of Edward and Elizabeth Brucker baptised 17th January 1789.  Wow, if this is the same guy at Rotherfield Grey in 1861, then his age is wildly out, and he fits into the age of my 1841 John after all.  It can happen.  They were old.  They could be deaf, or the person reporting to the enumerator could have had senile dementia.  A neighbour could have helped out, but got their ages wrong.  How many John & Elizabeth Brookers could be in the Rotherfield area?  I have yet another expensive Oxfordshire FHS parish register transcript CD-ROM on the way.  I feel increasingly pressured to spend a few days in the Oxfordshire and Berkshire record offices.  Long Wittenham has changed county.  It is near to Abingdon, on the south side of the Thames, and it was in Berkshire at that time.  It is now in Oxfordshire.  Drayton, is on the other side of the river, not far away.  The couple in must have met and married in that area of the Thames valley, and later, moved around twelve miles down river to the Rotherfield area.

Are they my 1841 couple though?  I have decided to add them to my tree - but subject to removal or verification, as I research them further.  If that baptism date pans out, with no earlier doppelganger being born in Long Wittenham, I'll start to feel happier.  If they do work out, then I have already found two new generations by the looks of it.  As I said above, this John, was the son of an Edward and Elizabeth Brucker.  He in turn, may have been the Edward Brooker baptised at Long Wittenham on 16th January 1757, to another earlier John and Mary Brooker.  It's taken me to a new and unexpected area of the Thames Valley.

Lessons to be learned

I doubt that anyone else ever reads these lengthy boring posts.  However should there be anyone out there, this is what I can pass to you:

• Internet Genealogy is hazardous.  Not just because of the forest of diseased, incorrect, badly researched, badly sourced trees out there, that Family History websites push into your face.  It is also hazardous because it is incomplete, but easy.  It is easy to believe that all paper records are online.  They are not by a long chalk.  Even the paper record is actually incomplete.  Many parish records have been damaged, lost, destroyed.  Some even evaded them.  Some have not been handed over to archives.  It is too easy with Internet Search to look for a Joe Bloggs, find a Joe Bloggs, any, and to grab them.  However, did you grab the right one?  Was it simply the only one on the Internet, in that particular database entered transcription?
• Don't be at a rush to grab your Joe Bloggs.  Take your time.  That is my weakness.
• Don't be afraid to have doubt.  Keep going back.  Check, verify, check again.

I've inherited from my father, a yDNA haplogroup of L1b M317.  Not a haplogroup ordinarily even regarded as European.  It's not particularly common anywhere, but of such low concentrations in North-west Europe, that it doesn't even appear on our haplogroup maps or tables.  Closely related L1a is concentrated in India, while L1c is concentrated around Pakistan.  But our sub clade L1b, has it's main concentration in Western Asia, south of the Caucasus.  It has been found for example in higher concentrations, in the Pontic Greek community that lived in Pontus, North East Anatolia, on the coast of the Black Sea.

I'm currently investigating the yDNA further with STR testing.  Unless the haplogroup was passed into our family at some point, via a non-paternal event, it should follow my surname line, which I've traced back to a John Brooker who fathered children in Oxfordshire during the early 19th Century.  The surname itself is certainly English.  It clusters in a few places in England - particularly in Kent / Sussex, although our family surname appears to have originated with a smaller cluster in the Oxfordshire / Berkshire area of England.  So how did we end up with an East Anatolian Y?

I quite like the below example of a similar, even more bizarre event in another English family, the Revis Family of Yorkshire, that share yDNA more normally associated with people in South-West Africa:

" ... it is surprising to find the haplogroup A1a (M31) in a family of the Yorkshire surname Revis. This haplogroup is close to the root of the human family tree and rare even in Africa. Genealogical detective work established that the Revis males who carried A1a fitted onto two family trees going back to the 18th century in Britain. A paper trail to a common ancestor could not be found, but genetically he can be deduced a few generations earlier. How A1a arrived in Yorkshire remains a mystery. As Turi King and her colleagues point out, it could have come via a round-about route and not carried direct from Africa.^{22T.E. King et al., Africans in Yorkshire?

Hey, Surnames, DNA and Family History (2011), p. 201-204.} A possible clue is that the surname Revis is derived from Rievaulx.^{23P.H. Reaney and R.M. Wilson, Oxford Dictionary of English Surnames, 3rd edn., revised (1997).} In 1301 a William de Ryvaus was the wealthiest taxpayer in Marton, North Yorkshire, about six miles from Rievaulx, and a man of the same name paid tax in Gisburne (Guisborough) about 12 miles north of Rievaulx, while a William de Ryvauxe was the sole taxpayer for Barnaby, in the parish of Guisbrough.^{24Yorkshire Lay Subsidy - 30 Ed. I (1301), ed. W. Brown, Yorkshire Archaeological Society Record Series, vol. 21 (1897), pp. 32, 43 bis, 45.} Rievaulx was a Cistercian Abbey in medieval times, founded from Clairvaux in France, and part of an Order with houses in Spain and Portugal built on land won from the Moors. No doubt genetic traces were left in Iberia of the Moorish centuries. A1a is not the most likely haplogroup to be among them, but perhaps not completely impossible. Master masons and other useful craftsmen could have been recommended by one monastic house to another in the Order. So we can dimly see one possible route from Africa to Yorkshire."

As for how our y-DNA may have arrived in Southern Britain, I can imagine a number of scenarios.  There is the early Neolithic hypothesis, that Y haplogroup L1b may be a remnant survivor of early European populations that had settled Europe before they were largely displaced during the Bronze Age, by DNA from the Eurasian Steppes.  But if that were the case, I'd expect it to be less rare.  L1b is scattered in low frequencies across Italy, and along the South European coast of the Mediterranean.  For that reason, it may be that it arrived here, or gradually made it's way across the Continent via the Roman or later Byzantine Empires, from Pontic Greek communities.  That is one possible route.

My Y Haplogroup L-M20 Resource Post

Edit. 03 May 2016

I've listed the origin (and sometimes origin or ethnicity) of all of the L-M317 listed on the Y haplogroup L project at ftDNA.  Including both SNP confirmed, and predicted:

Ten from Turkey (two specified as Armenian)

Five from Georgia

Three from Chechen Republic

Two from Greece (one specified as Pontic Greek)

Two from Portugal

Two from Italy

Two from Armenia (one specified as Turkish)

One from Iraq (Assyrian)

One from Kuwait

One from Azerbaijan (Azeri)

One from Lebanon)

One from Bulgaria

One from Austria

One from USA (surname Ayers)

One from Romania

One from Russia (Tatar)

One from Cyprus (Austrian Tyrolean)

In addition to these M-317's, there is the Pontic Cluster (L-PH8 (FTDNA L-M317) YCAii = 17-21) of 56 individuals, many only low level STR tested to predict L-M20.  Some of them however, are tested down to M317.  They are mainly in Turkey, Georgia, Iraq, and Greece.  One however, was in Germany (surname Stiffler).

Where will our L-M317 fit in?  Which of these will turn out to be my nearest cousins?
