If anybody is interested, my DNA Deep Subclade Test reveals R1b1c6 - An Iberian Haplogroup that may have migrated some time from approx. 3580 ya (1580 BC) estimated by Hurles, et al and most likely arrived out of Iberia (possible modern Basque Country) to SW England. My Oppenheimer Test results in what he has analyzed as "Ruy" or cluster R1b-10 which is related to the R1b Atlantic Modal Haplotype descended from Rox R1b-9 (Basque Modal Haplotype). The data given by Dr Sykes (Oisin) and by Oppenheimer (Ruy) is very generalized. The haplotype associated is known as Western Atlantic Modal Haplotype, the haplogroup is R1b1c6 which is mostly found in Basque Country 11-12%, Catalonia 22-23%, and smaller numbers in Andalusia (Malaga, and Huelva). It is interestingly found at around 12% in the Canary Island of El Hierro, and a lower percentage on Fuerteventura Island. R1b1c6 is also known as SRY2627, M167, R1b3f, R1b8, HG22, and some older designations. It is currently mostly found in SW England in higher numbers (Devon, Somerset), Wales and Ireland.
I'm awaiting autosomal test results to specify more details of my genetic "history". R1b1c6 is not a very common haplogroup and in a way this is encouraging as indicators of localized origin is easier to identify. There is a debate going on about DYS value 448=17 being perhaps a Welsh Modal marker. I hope this to be true, and have been playing devil's advocate to ensure accuracy of such claims. Researching the data found on Dr. Sykes of Oxford Ancestors there may be some truth to this as the haplotype I am assigned to (though haplogroup has a very low worldwide population) reflects to be most commonly found along the southern/southwestern Wales and SW England.
I'm hoping to identify the surname and relation with the placenames of the streams/rivers found most commonly in SW England known as Congresbury Yeo near Bristol, Land Yeo, Blind Yeo, Cheddar Yeo, Mark Yeo, Yeo (Exmoor National Park), Yeo (Dartmoor National Park), Yeo (Exeter), etc.
Though I have given some serious thought the origin may be from Gascony/Aquitaine region of SW France/Basque Country. Eau is commonly identified with water, Aquitaine has been speculated to be related with water, ocean/rivers/streams, and Yeo perhaps might be a cognate with Eau rather than the Germanic Gau (district). The Yeo rivers appear to be rivulets draining the moorlands mostly into the Bristol Channel and some into the English Channel. Coincidence?
I would also be interested to see whether or not there's any sort of connection to the Yeo rivers/streams of SW England and the points of origin of the Thames and Avon River in the Cotswolds region long associated with sheep farming and yeoman farmers. Basques/Gascones are renowned sheep farmers as well sailors/fishermen. Sykes mentions that most Britons are descended from a tribe of Iberian fisherman that arrived some 6,000 to 7,000 ya (awaiting for his book Blood of the Isles). Have been reading Dr. Oppenheimer's book "The Origins of the British" A Genetic Detetive Story. I have also read Sir Barry Cunliffe's Book "Facing the the Ocean", as well Francis Pryor's Britain AD and Britain BC (all good reading material) to help validate the analysis conducted on my yDNA.
Several research papers such have been conducted on Basque DNA, Genetic Drift, etc. (too numerous to mention them all, but nonethless good informative material). By and large John McEwan's website has been one of the most informative: www.geocities.com/mcewanjc/m167.htmAnother person that seems to be well informed of SRY2627 is Ellen Levy-Coffman and discussion threads can also be found on rootsweb. Very interesting stuff that I have learned over the last year, after Ancestry.Com failed to yield results going back no further than 1886 with my ancestry.
Sorry for all the tangents, but I'm attacking this at all angles possible. Any male Yeomans, or variants of the surname who wish to have their Y chromosome and autosomal DNA tested please contact me, as I would like to initiate a surname project in the near future to reduce costs for any persons willing to donate genetic material for yDNA analysis.
