Genetic Genealogy - who was my great grandfather?

During the Black Friday sales last December, I bought two Ancestry kits. I actually mean't to order one, but made a bit of a mess of it. Still, I thought, they were as cheap as I've seen a DNA kit, so I let the order process.

Some people might exclaim - but you've tested your DNA to death!  These kits were not directly intend for myself though.  I intended them for the art of Genetic Genealogy.  To help me verify my paper tree, biologically.

Although I enjoy the kick that I get from matching segments of DNA in strangers, to shared ancestors of the past on all lines, I'm particularly interested in one line, from one great grandfather.  You see, I had a very naughty great grandmother.  I have uncovered evidence of two bigamous marriages by her, as well as other relationships.  A second cousin of mine, through her, doesn't appear to have the amount of shared DNA that I would expect for a full second cousin.  It looks worse than even the old family rumours.

As I do have an extensive family tree down to that birth certificated great grandfather, even though I know full well that biological family isn't always as good family as non-biological, which the paper trail honours, I'd still like to know.  With Genetic Genealogy, I hope to verify - or otherwise, his biological relationship.

So... I used one kit to test one of my siblings, and the other to test my mother.  I've tested my mother before on 23andme.  Mistake.  I've learned a lot about DNA testing over the past few years or so.  Ancestry.com might seem like a heavy marketing, greedy big DNA company, with some slightly dishonest sales ploys (find out if your ancestor was a Viking!), and pressure to subscribe to more services in order to get the full benefit of the test - BUT ... it 1) has an awesome family tree building website for subscribers, that link to DNA tests, 2) has the largest customer database, and 3) through it's genealogy services, as well as marketing, has the most UK testers in it's database.

Okay, it's a little dumbed down.  The messaging system sucks (so I always send my email address), It doesn't provide a chromosome browser.  It doesn't provide segment locations on chromosomes.  But - for my uses - using DNA matches to verify a family tree pedigree, it serves extremely well.  I have had almost ten times more matches on AncestryDNA, than from 23andme, FT-DNA, and GEDmatch combined.  And many have online trees!

I've received my siblings results.  Wow.  I suspected it.  That the sibling has inherited some quite different DNA from the parents mean't that although we share some DNA matches, there are many that we don't!  Up to now, I've just used a spreadsheet to keep results of verified matches.  I could see that I now need something more powerful.  Something that I could search on - and filter different lineages.  When my mother's results arrived, I'll be able to divide all of my matches into maternal, or paternal sides.  On top of that, I have a 1C1R (first cousin once removed) on my father's side, that I can sometimes use to indicate some ancestry on his side.  I can look at all of my matches and their shared matches, and triangulate, where abouts they fit into my family tree.  I built a personal database for my DNA matches.

So I'm pretty pleased that I invested in those two kits during the sales.  It's kept me busy.

I used Open Office Base to build the database:

Okay it's basic and not pretty, but I can extend on it.  I've imputed our closest 187 DNA matches, nearly all from Ancestry, plus a few verified from FT-DNA and GEDMATCH.  It's a family match - I've included forms for imputing my mother's and sibling's matching segments - not just my own.  Any genuine matches that my sibling has - are also my cousins.  Just that I don't have personally share DNA segments with them.  I've also included a yes/no check box for that 1C1R.

I've used it to query an up-to-date list of "our" shared DNA matches that share a correlating common ancestor or two on their trees with ours.  My biological "verifiers".

Using the open source GRAMPS app, I produced a fresh family pedigree fan chart.  I then used open source GIMP to colour in the ancestors that I have verified with shared DNA segments.  The darker the tone, the more matches:

It's generally looking pretty verified isn't it.  My birth certificate grandparents were all very clearly, my biological grandparents.  The great grandparents, and the majority of great great grandparents are also looking pretty verified.  But what about that great grandfather?  The birth certificate version was my surname great grandparent, and biological version was my Y-DNA great grandparent.  Were they the same?

Well I still do not have evidence that I'd regard as overwhelming.  But I am gathering evidence that he may have been the same guy.  I have two DNA matches that strike directly through him.  Unfortunately, both were distant ancestry, with only a small shared segment each (around 7 cM).  That small, they could either belong to an undocumented relationship elsewhere, or even be identical but not by descent.  But it's evidence that I'm building, and it's more reassuring than if he'd had no DNA matches strike through his lineage to us.  The other supportive evidence was that my biological paternal line great grandfather carried an incredibly rare haplogroup: Y haplogroup L-SK1414 (L1b2c).  The only other L-SK1414 so far found in the British Isles, traced his paternal surname line back to Basingstoke, around 1740.  My documented surname line traces back in 1740 to Long Wittenham, Berkshire.  Only about 32 miles away from the Basingstoke L-SK1414 by road.  Could be a coincidence, but it supports that the Y-DNA could still correspond with the surname line back in 1740, and that my great grandaddy, was my DNA great grandaddy.

Such is the power of genetic genealogy.  Roll on the results of my mother.  That will reduce the number of matches that are likely to be on my paternal side.

Brooker Surname and a new project

Above map modified from "© OpenStreetMap contributors".  The red dots represent baptisms of BROOKER (including derivations such as Broker, Brocker, etc) between 1550 and 1600.  The larger the red dots, the more baptisms in that parish.

The area focuses on South-East England.  There was also a secondary cluster in Warwickshire, and stray families in Manchester, Yorkshire, Devon, and Norfolk.  However, I have not catered for all of those on the above map.  See the below larger scale map for Brooker baptism counts in those areas by county.

The Blue dots and notes mark ancestral birthplaces and dates of my recorded surname ancestors in Berkshire, Oxfordshire, and Deptford, London.  My line traces back reasonably securely to a John Brooker born at Long Wittenham, Berkshire, circa 1722.

The Purple dot and text represents Thomas Chandler of Basingstoke, Hampshire.  Living there circa 1740's, he appears to have shared my Y-DNA markers L-SK1414 judging by some of his Chandler surname descendants that have tested.  At some point before 1722, we must have shared Y line (paternal) ancestors.

From this map I can conclude that during the late 16th Century, the BROOKER surname was most common in Sussex, Kent, Surrey, and Hampshire.  There was a secondary cluster in Warwickshire.

Surname Origin

This interesting surname derives from two possible origins. Firstly it may be of English topographical origin from the Old English word "broc", a brook, stream, plus the agent suffix "-er", used to describe a dweller at, hence "dweller at the brook". There is also a place called Brook in Kent and Wiltshire, from the same Old English word "broc" as above. Also the name may be an occupational name used to denote a broker, originating from the Anglo-French word "brocour", one who sells an agent in business transactions. The earliest recordings of the surname appear in the 13th Century (see below). John le Brouker was recorded in the 1327, Subsidy Rolls of Sussex. William le Brocker was listed in the 1326, Feet of fines Rolls. The Close Rolls in 1332, record a Elena Brocker. Kirby's Quest for Somerset recorded an Adam Brocker in 1328. Geoffrey Broker, aged 17, an immigrant to the New World, sailed aboard the "Merchant's Hope", bound for Virginia in July 1635. The first recorded spelling of the family name is shown to be that of William Brokere, which was dated 1296, Subsidy Rolls of Sussex, during the reign of King Edward 1, "The Hammer of the Scots", 1272 - 1307. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.

Discussion

A weakness with the data will be that the sources may be selective and biased, due to incomplete transcripts, register survivals, etc.  However, it gives me an indication of just where my surname may have originated before John Brooker married Mary Gardiner at Oxford College chapel, on the 1st November 1746.  They were recorded as residing at Long Wittenham, Berkshire.  Mary Gardiner appears to have hailed originally from a family a few miles to the south of Wittenham, at East Hagbourne in Berkshire.  I also found families of Brooker in that same parish, including a suitable John Brooker candidate born in 1722.  However, on reflection, and in discussion with another researcher that also claims descent from the Hagbourne John Brooker, I decided to delete that connection.  Hagbourne John Brooker married another woman, not Mary Gardiner, and did not move to Long Wittenham.

I then chose the next best candidate.  Further afield, a John Brooker born 1722 at Chieveley in Berkshire.  I have to confess a bias to that direction as it lead towards Basingstoke (I'll get back to that further down).  However, once again, I can see evidence to eliminate him.  I need to consider another John Brooker at Oxford next.  So many John Brookers!

Why am I looking for a link to Basingstoke?  Because several people that have tested their Y chromosome DNA with Family Tree DNA, appear to have the same Y DNA data as myself.  Incredibly rare, and hailing from Western Asia, L-SK1414.  These several other testers are all from the paternal surname Chandler.  They form a small but distinct cluster in the Chandler Surname Y-DNA projects, very distinct from other Y-DNA in the group.  Some of them have traced their surname lines to a Thomas Chandler, that lived at Basingstoke early to mid 1700s, the same time as my 6 x great grandfather, John Brooker that married Mary Gardiner and settled at Long wittenham.  Basingstoke is about 32 miles south east of Long Wittenham as the crow flies.

At some point, the Y-line descendants of Thomas Chandler, and myself, must have shared a common Y grandfather.  Some point most likely between 2,000 years ago, and 400 years ago, and most likely, in Southern England.  Convenient for the Coast and for ports that our Asian Y ancestor may have arrived at by vessel.  Most likely I feel, in the Sussex or Hampshire region.  Look at the clusters in the top map around Southampton, Chichester, and Brighton during the 16th Century.

That I haven't found many Berkshire, and only one Oxfordshire Brooker baptism between 1550 and 1600 could suggest that my surname most likely trails down through Hampshire between 1600 and 1746.  There is always however, the possibilty of a relationship in the other direction to the Gloucester cluster.  That goes against the Basingstoke Y hypothesis, but it is a possibility.  Where did the Gloucester cluster originate?  For that matter, where did the more significant Warwickshire cluster originate?  Did it move there from South East England during the medieval, or does it converge from an independent surname origin?

If the surname line is still true to my Y-DNA at Generation 9 (John Brooker of Long wittenham), and the existence of the Chandler L-SK1414 does support that my Y-DNA most likely would have been in that part of Southern England at that time, then just when did the Brooker and Chandler families last share a common Y-DNA father?  The convergence could be the result of a non parental event in either direction.  Even a series of non parental events.  Alternatively, it could predate the emergence of peasantry surnames during the 14th Century.  The above quote from the surname website suggests some aristocracy were using the surname as early as AD 1296.  However, many peasant and commoner families would have been slower at adopting a surname.

Brooker Surname Study

But for now, I'm stuck at that marriage in 1746.  Therefore I'm launching a longer term surname research project, starting with collecting baptisms of Brooker, Brocker, Broker, Browker, etc. Between 1550 to 1600, and then moving forward.  Screenshots of my baby database below:


Was our Y ancestor a Druze?

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

The Druze are a Levant community, dispersed primarily through Syria, Lebanon, and Israel.  They consider themselves an Arabic culture, but they follow their own faith system, which according to Wikipedia: "The Druze faith is a monotheistic and Abrahamic religion based on the teachings of Hamza ibn-'Ali, al-Hakim, Plato, Aristotle, Socrates and Akhenaten.".


What makes the Druze particularly interesting to population geneticists, is that they stopped accepting converts one thousand years ago.  They marry within their community only.  Therefore they potentially represent a snapshot of the medieval Levant population, without more recent admixture.  A recent genetic study of the Druze confirms this history:

"The researchers also found that there is no evidence of new genes entering the Druze gene pool over the last 1,000 years. In other words, no additional groups from the outside joined this community. In addition, the researchers found evidence of genetic differences between Druze populations from different regions: Lebanon, the Golan Hights, the Upper Galilee and the Carmel Mountain. This strengthens the evidence that marriages take place only within each clan.

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.".

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!

Was our Y ancestor a Baloch Lascar?

See page for author [Public domain], via Wikimedia Commons.  "A Portrait of an Indian Gentleman," by A. Smith, 1841.  No.  This portrait was not one of my ancestors.  It is believed to have been painted in England.  However, my Asian Y ancestor must have been here previous to 1700.  This relates to my Y line, inherited down my father's, father's father line and so on.  Descendants for example of Reginald J Brooker, should share this heritage.  My Y-DNA research indicates that I had an Asian ancestor, that most likely moved to Southern England sometime between 1,800 and 500 years ago.  I did find this portrait however, on Wikimedia Commons, whilst searching the subject of who my Y ancestors in Asia were, and why one may have travelled to England.

Let's start a little further back.  My Y-DNA is West Asian in origin.  I share my current terminal Y-DNA SNP (L-SK1414) with a guy that is a Balochi speaker from Makran in SW Pakistan, close to the border with Iran.  I also match fairly well (on STR tests) with a guy who's paternal line hailed from the town of Birjand, South Khorasan, Iran.

Now, although my Australian Y cousin with ancestry in South Khorasan didn't know of any family Balochi link - it's possible.  Balochi, have lived in that region of Eastern Iran.  It may, just may, be a link.  Who are and were the Baloch?

Origins of the Baloch People

See page for author [Public domain], via Wikimedia Commons.  Iranian Baloch khans in Qajar era, c. 1902.  The Baloch people today are spread across Western and Central Asia, mainly found in SW Pakistan, SE Iran, and Afghanistan.  

The pink areas display the main Balochi areas today.  The red outline suggesting likely homelands for my Y-DNA.  Also marked by red spots, are the homes of the two recorded L-SK1414 in that area.  It is estimated that there are 15 million Baloch people across the World today.  The Balochi language is Iranic.  It has been ascribed by linguists as belonging to the North-West Iranic family, close to Kurdish.  Yet the Balochi today, are in the South-East of the Region.  The traditional origin story told by the Baloch people, is that they were Arabic, and originated in Syria.

However, linguists and historians today usually suggest that they were in fact, refugees from Arabic expansion, that migrated mainly east and south east, over several centuries (starting circa 7th Century AD) from an area close to the Caspian Sea in Northern Iran.  This puts Birjand incidentally, on the route of that migration.  It also leads from what I consider to be the homelands of the mother clade - Y hg L1b (L-M317), between the Caspian and Black seas.  Today, the majority of the Baloch are Sunni Muslim (some are Shia).  However, many early migrants from the North West may have ascribed to other religions including Zoroastrianism.  An attack on Persia by the Seljuk Turks from Central Asia during the 11th Century AD, may have accelerated Baloch migration to present day Balochistan. Today, the Baloch of Pakistan, Iran, and Afghanistan are divided into an estimated 130 tribes.

As for Balochistan itself, when Alexander of Macedonia, passed through it, during the 4th Century BC, it was known as the Kingdom of Gedrosia.  Balochistan has long been sandwiched and pulled between the great empires of Persia, and India.  Even today, it is divided between these two political boundaries.  A large region with a sparse population, but a firmly stamped ethnic identity.

According to Akhilesh Pillalamarri "In the 1500s, Balochistan like Afghanistan to its north, became divided into zones of control between the Safavid Persian Empire to its west and the Mughal Empire to its east. This approximately reflects the Iran-Pakistan border today."

Could this friction even have lead my Y ancestor to move?  When did European ships appear on the coastline?

That's the Baloch hypothesis.  Now for the next, the Lascar hypothesis.

The Asian Lascar

By National Maritime Museum from Greenwich, United Kingdom [No restrictions], via Wikimedia Commons. Three lascars on the Viceroy of India.

Our Y ancestor may have moved to Southern England for all sorts of reasons:  merchant, diplomat, adventurer, slave, hostage, prisoner of war, trader, mercenary, servant, religious convert, refugee, etc.  Genetic genealogists tend all too often to cling to known historical events such as battles.  I'd be very wary of that. 

With that in mind... here is one new possibility (as opposed to a probability), that I am presently considering.  

The Lascar.

Lascar derives from al-askar, the Arabic word for a guard or soldier.  When European ships first started to sail the trade routes to India and the Middle East, they often suffered losses of life on the way.  Subsequently, they would recruit new sailors at their ports of call.  Arab traders had scattered seamanship and sailing skills along the coast line around the Persian Gulf, and the practice of Lascars may have already been established before the first Portuguese ships picked them up.  The European practice of taking on Lascars is believed to have started as early as the 16th Century.  It continued through to the 20th Century.  Just about in time, to account for my Y-DNA in Southern England, that turns up during the early 18th Century in two surname families.  It's possible.

Apparently, the Lascars received even poorer food and water than even the late British sailors that they replaced.  Therefore, many jumped ship when they reached England.  Their intentions may not have been immigration, but they couldn't risk the return voyage.  This, it is said, was the very first root of the present day Asian settlement of Britain. It has been speculated that the portrait at the top of the post, may have been of a former Lascar, or ... servant!  Why not though, a traveller that has succeeded?

Why would a 16th or 17th Century European trading ship visit Balochistan?  Did it?  Our ancestor may have already moved either westwards or down to an Indian port.  He may have been a professional sailor!

It's one possibilty.
