Ancestral Family Tree DNA Testing / Re: S27900 marker
« on: Tuesday 12 November 19 21:23 GMT (UK) »
Hi,
I am the volunteer administrator of the FTDNA Williamson Surname Project. I have a cluster of S27900 descendants who come through Y81518:
S27900 > FGC39551 > FGC53441 > FGC39549 > FGC39559 > BY19604 > Y81518
The surnames that belong to this SNP include Williamson, Smith and Price. Immediately upstream, we then have Williams, Lewis, Jenkins, and Evans at BY19604. The group of 11 Big Y participants at BY19604 average only 5 mutations, which suggests that it is reasonably recent and perhaps within the timing of written records; STRs likewise seem to support this possibility.
Llanfihangel mentioned that patronymics were still common in Wales before 1700, meaning that a family line could have several generations of closely related individuals migrating off to the American Colonies through the late 1600s to early 1700s, but each then having a unique surname here in the States. Have any of you looked at your early lines to identify surnames that branched off of them?
Llanfihangel, you seem to connect in with this group at FGC39559, which has some 21 participants with Big Y averaging only 8 mutations, so not too much further out. Do you have a public tree of your pre-1800 ancestors that I could take a look at in considering this question? I saw that one of the Williams lines within R-S27900, who is not too far removed from our Williamson group (Y111 GD6), taces his line to an "Ellis ap William ap Hugh, b. 1590 Merioneth Wales"; with that name itself allowing for lines of surname Williams, Lewis, and Pugh if any of those three generations were to leave patronymics in favor of a consistent surname (noting that Williams, Lewis and Pugh are all surname clusters within the R-FGC39559 branch).
