Any Welsh origin Sinnetts here? Or anyone in contact with Sinnett families who have family origins in Pembrokeshire? The Sennett (Sinnott, Synnott, Sennett, Sinnett, etc) DNA project at familytreeDNA has recently had an incredibly interesting Y-DNA (BigY) result that confirmed the genetic relationship of a Pembrokeshire Sinnett family to Irish Sinnotts/Synnotts, in about the timeframe where this group of surnames first became established (12th century). The surname project (at familytreedna dot com) is now really keen to have people from two or three more SINNETT families with Pembrokeshire ancestry join, in order to try and triangulate results and pin down the date of common ancestry a bit closer. There are some sponsored tests available for either an initial Y-DNA37 test, or for BigY upgrades of lower level Y-DNA tests from Sinnett men who show an E-M35 haplogroup. Best way to contact me is through the surname study contact link (use the search box on the Guild of One Name Studies website, or the contact form on the Sennett surname study website).
The surname study is also very interested in getting a whole lot more families of any spelling variant of S-NN-TT (one or two N's or T's and any vowels) and any origin joining the YDNA project. With more than 30 DNA tests having been upgraded to BigY so far (many of these upgrades being sponsored by the project) we are building an incredibly interesting genetic tree that so far links many different surname variants, and Irish, Welsh and Cornish origin families to the same 12th century common ancestor.
