Re: Phillips Big-Y - new Bennett/Phillips branch

Charles Thomas

Thanks for the update. I checked and yes FTDNA does indeed show me as R-Y29969 now with BY11573 shown in light brown meaning presumed positive beside Y29969 on the tree. I also noticed that Rodney Martin is shown as BY11573 on my match list.

Thanks also to Joel a week or so ago for the heads-up on the YFull tree update.

Subject: [Z16357] Phillips Big-Y - new Bennett/Phillips branch
The Big-Y results for Brent Phillips are in. He is confirmed R-Y29969
with Bennett and Thomas. This is phylogenetically equivalent to
BY11573. You'll notice FTDNA has changed the terminal SNP for Bennett
and Thomas to Y29969 - it's a more reliable SNP to check.

Beyond this, there's also a new tentative Bennett/Phillips branch.
They both share the following markers (and perhaps some others that
are yet to be discovered):

These are in rather poor read areas for the Y-DNA test, but I believe
at least the first one should hold up under further analysis to create
this new branch.

I had thought that Bennett and Phillips would share more good SNPs
(i.e., they had a more recent common ancestor), but this proves that
their lines split after Y29969. But both of them have around 10 good
unique SNPs that would provide distinct Bennett and Phillips branches
with additional cousin testers.

Another good discover with the Phillips and my Smith Big-Y is
validation of 5 or 6 other SNP markers that those of us on the Z17911
block share. This means that Z17911 is a bigger/longer block than we
had previously thought, thus moving our more recent ancestor in that
block closer to modern day.

My own VERY rough estimate based on what we know now is that our most
recent Z17911 lived probably around 1200 years ago, with the
Bennett/Phillips/Thomas/Merrick/Goff Y29969/BY11573 ancestor living
around 800 years ago.

Brent's results add some very useful information to our project!
