Hi David, Kevin and other Pikes,

I am the group administrator for the Baughan DNA project.

I have a comment on your discussion below of Kevin Pike's results.  As you
have correctly pointed out, Kevin matches exactly on 67 markers the modal
haplotype for a group of men with surnames like Farris, Baughan and Stone.
Farris seems to be the root name of this haplotype. Many of these Farris men
were first tested by DNA Heritage and have since converted over to FTDNA.
One of the markers tested in DNA Heritage's standard 43 marker test is a
marker called GATA A10.  This has proven to be a very significant marker for
delineating Farris men into two subgroups.  The modal value across all men
tested for this marker is 14.  A group of men who all trace their personal
ancestries to a certain James Esom Farris, share a value of 12 on that
marker.  This is significant because the most likely explanation for this is
that James Esom Farris or his father had an extremely rare two-step mutation
on that marker.  Some time ago, I read up on the probabilities of a two-step
mutation occurring in a single meiosis event and while I don't now remember
the actual probabilities, I think it is on the order of 1 in 37000.  

All of the Baughan men and most of the Farris men share a value of 14 on
that marker.  Kevin had himself tested for that marker and his value is also
12.  Because of the extreme rarity of the occurrence of a two-step mutation,
it is my opinion that Kevin descends from the James Esom Farris branch of
the Farris family.  As of the last time that Kevin and I discussed this, my
recollection is that he still has no idea how that line of descent occurred.
In the timeframe of 1748-1750, James Esom Farris owned land in an area of
old Lunenburg County that later became southwestern Charlotte County.  Later
he bought land in present day Pittsylvania County.  Ultimately, he and his
family migrated through Kentucky to Tennessee and beyond.
