The Other SK1414. My Cousin in Baluchistan

By Baluchistan on Flickr under a Creative Commons Licence. No, this young man is not the SK1414 tester, but the mandolinist in me found this photo kind of cool.  A young man from Makran.  The other SK1414 tester was also a male Makrani Baloch.

I'm hot on the trail of my Y or paternal line, following my FTDNA Y111 STR, then Big Y tests.  These tests analysed the DNA on my Y chromosome.  It is passed down strictly from father to biological sons.  the mutations (SNP and STR) that can be identified in the Y-DNA, can be used to assess relationship, and in some cases, to date the time of most recent common ancestry.  So, with the assistance of Gareth Henson, administrator of the FT-DNA Y haplogroup L Project, and with help from my new distant cousins, what have I learned over the past few weeks?

The Smoking Gun of Y-DNA

Between 45,000 and 13,000 years ago, my paternal ancestors most likely were hunter-gatherers, that lived in the region of what is now Iran and Iraq, during the last Ice Age.  Some sharp changes in glaciation, and cold extremes towards the end of that period, may have generated a number of adaptations, and subsequently, split new sub clades of my Y haplogroup L.

13,000 years ago (based on the Big Y test), I share a common paternal great x grandfather with a number of distant cousins, that descend from Pontic Greek families from the Trabzon region in Turkey.

Between 3,000 and 1,000 years ago (based on the less accurate STR evidence at 111 marker), I share common paternal great x grandfather with another cousin, who's paternal line Habibi, can be traced back to the 1850's in the town of Birjand, Southern Khorasan, Eastern Iran, close to the modern Afghanistan border.  This closer cousin now lives in Australia.

My Big Y test produced no less than 90 previously unrecorded or known SNP (pronounced "snip") mutations.  That might be because my Y-DNA is rare, or / and, that it is mainly found in parts of the World where very few people test at this level.  The last SNP on the roll that had been seen before, has been called SK1414.  Because now two of us have tested for this SNP, it is my terminal SNP, so at the moment (although it still has to be submitted to the YFull Tree), I can declare my Y haplogroup sub clade designation to be L-SK1414.  Only one of two so far recorded in the World.

So, who is this Y cousin that shares my SK1414 mutation?

My Baluchistan Cousin

The other SK1414 turned up during an early survey, back in the early 2000s by the Human Genome Diversity Project.  It turned up in a sample of the Baluchi in Makran, South-west Pakistan.  Could this cousin be closer than the Habibi tester?  Could my Habibi cousin, from an eastern Iranian family also carry SK1414?

The Baluch, are an Iranic people, that speak Baluchi, an Iranian language that belongs, as do most European languages, to the Indo-European linguistic family.  According to the Iran Chamber Society website, they moved to Makran during the 12th Century AD.  Traditionally the Baluch claim that they originated in Syria, but a linguistic study has instead suggested that they actully originated from the south east of the Caspian region, and that they moved westwards between the 6th and 12th centuries AD in a series of waves.  No other Y sub clade L1b (L-M317) have been found in Southern Asia outside of two samples of this survey, so perhaps the tester did have ancestry from Western Asia.

It would seem likely that I do have a number of Y cousins, most likely in the region of Eastern Iran and South-Western Pakistan.  That doesn't necessarily follow though, that our most recent common Y ancestors lived there.  As I said above, the Baluch of Makrani, Pakistan are said to have migrated from further north-west, from the Caspian Sea region.

There is a tentative suggestion of a link to the Parsi. A Portuguese STR tester with a genetic distance (based on 67 markers) of 22, has (thanks again Gareth) "a distinctive value of 10 at DYS393. In the Qamar paper this value is found in the Parsi population".  So there is just the possibility also, of the Parsi ethnicity carrying L1b from Western Asia into Southern Asia.  Perhaps this marker was picked up by a Portuguese seafarer link to Southern Asia.  It could even be the link to my English line, via the Anglo-Portuguese Alliance.  A lot of speculation.  I don't think that M317 has been found yet in India.

Into England

I have found STR links with four people that carry the surname Chandler.  They live in England, Australia, and the USA.  These cousins appear to descend from a Thomas Chandler, that lived in Basingstoke during the 1740s.  That is 32 miles away from my own contemporary surname ancestor, John Brooker, who lived at the same time at the village of Long Wittenham in the Thames Valley.

Unfortunately three of the Chandlers have only 12 markers tested, and the fourth at 37 markers.  Therefore time of most recent ancestor is not accurate, but it looks as the Chandler and Brooker Y hg L testers of Southern England, most likely shared a common paternal great x grandfather sometime between 800 and 350 years ago.

That only these two lines have turned up, and that they are geographically and genetically so close, might suggest that our Y-DNA lineage arrived in Southern England around the late medieval, perhaps from between the 13th and 17th centuries AD.  It could just be through a Portuguese navigator link, or it could be through thousands of other routes.  More L-M20 testers could turn up in England in the future, that could push the arrival to an earlier date.

Today

I could have any number of cousins from south England.  The Brookers and Chandlers may well have other paternal line descendants living in the Thames Valley, Hampshire, London, or elsewhere.  I'd love to prove a Brooker from the Berkshire / Oxfordshire area, as sharing ancestry.  I believe for example, that the journalist Charlie Brooker descends from one of the Thames Valley families, although not necessarily from mine.  Do they carry the Y hg L?

My great great grandfather Henry Brooker, did not appear to have any more sons, other than my great grandfather John Henry Brooker - who in turn, only had one son, my grandfather Reginald John Brooker.

I have one Y haplogroup first cousin.  He has I believe, a son, and a grandson.

The Chandler-Brooker Y haplogroup L1b (L-M317)

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.

The Chandlers of Basingstoke

The FT-DNA Chandler Surname Project is very well managed through the Chandler Family Association.  The three Y12 test kits, that hail from a Basingstoke ancestor, and have proven to belong to the exclusive L M20 Y-DNA haplogroup, have been clustered together as Chandler Group 10.  If our surname was Chandler, rather than Brooker, my Y111 results would fit perfectly into this cluster.  This is because we shared a common paternal lineage, until between 500 and 320 years ago.

Origins of the Chandler-Brooker L1b Y haplogroup

That one has still to be answered.  I'll be consulting others, the Y haplogroup L project administrator, and looking forward to my Big Y test, which is scheduled to take place soon.  However, judging by how very few L-M317 Y haplogroup carriers have so far been recorded in the British Isles, or in North West Europe; I'd dare to propose that the common paternal ancestor of both lines, most likely had not been in England for very long.  Perhaps they could for have example, have carried the Y-DNA here as a 16th or 17th century protestant refugee?  Maybe not, they could have equally been a merchant, an artisan, a servant, a mercenary, or have arrived in another capacity - if indeed they did arrive here that recently.  There is no indication in neither the Brooker or Chandler surname of anything but a medieval English origin (unless originally Bruche, or Chandelier?).

If the common ancestor did arrive that late, where did he come from?  What modern population elsewhere most resembles his Y-DNA?  Hopefully, the Big Y test will help to answer that.  Meanwhile my untrained eyes see correlations within many of the STR markers of people that descend from the Pontic Greek community, that once lived in Eastern Anatolia, and around the Black Sea area of Western Asia.  Of course, the Y-DNA might not have been carried to Southern England from such a homeland within one generation.  It could have been?  There is no sign of any West Asian, Balkan, or Caucasus ancestry within my autosomal DNA.  However, even six to eight generations ago - that could be washed out through recombination - leaving only the Y-DNA to tell what would have otherwise remained a lost untold story.  However, it could have moved across via a number of generations.  It will be worth looking out for any evidence of this on results across the Continent.

Kit Number 26369

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?

STR:

Time will tell.  My Y111 test should take place within the next month.
