View Full Version : J-Z18186 Haplogroup

05-16-2015, 09:06 AM
One of my surname group has an extremely rare, (for our surname), haplogroup. He tested FTDNA's new SMS-M267 SNP pack & is now classified as J-Z18186. I have a strong suspicion regarding how & why this haplogroup appeared on the Anglo-Scottish border. Does anyone else belong to this haplogroup?

Whereabouts England are you from? Is your surname common? Like taylor or reid?

The surname originated in Cumbria in 1223. It's common for the border counties. I'm R1b, and our surname's mainstream is massively R1b, hence the interest in this unusual haplogroup. I suspect a conscripted Middle East legionnaire may have had some input.

I suspect you're referring to the Jordan-Graham cluster, which is J1-L1253. L1253 is a subclade of Z18186, its TMRCA is ~500 yBP. The "Syrian auxiliary archers" theory has been a long-time favourite explanation for this particular cluster's origins, as it belongs to a seemingly Arabian branch of YSC76 mainly distributed around the Gulf (this could be due to sampling bias though) however the TMRCA estimate doesn't really fit with this scenario.
There's a parallel (Z18186-) branch called ZS1559, which has a cluster entirely made up of people from the British Isles (England in particular), IMO J1-ZS1559 is a stronger contender for the "Syrian auxiliary archers" theory.

You might want to have a look at the J1 FTDNA project (https://www.familytreedna.com/public/J-M267/default.aspx?section=yresults) and see whether you can spot your surname.

Yes, that's the Jordan-Graham cluster. They share Z18184 with Arab individuals (FTDNA#215410,M8961) and the chronology would depend on the number of SNPs. "Syrian archers" or "Saracens" during the Norman conquest could be possible.

The gentleman concerned's ancestors have farmed within five miles of Housesteads & Carvoran Forts since the mid-1600s. Both those forts protected Hadrian's Wall. For those reasons, I was interested when I saw his haplogroup designation, particularly as Hamian (Syrian) archers were stationed in the vicinity.
