I know that many people know very little about Y Chromosome DNA
and it use in genealogy, and especially among females since Y Chromosome
DNA is transmitted only from father to son. It is a fairly complicated subject
but I intend here to simplify it somewhat.


First of all, I am a member of the Family Tree DNA Walker surname group
and am in subgroup #1. Subgroups are supposedly groups that are assumed 
to be closely related in time; that is they should have a more recent common 
ancestor. There are currently 592 (I think) Walker members comprising 20
to 30 different family subgroups. I am in subgroup 1 since I was in the first
group to submit DNA for the Walker surname.


In FTDNA Group1 there are currently 23 members, including myself. Now, my
Y- DNA should be the same as my gr gr grandfather, Samuel Walker and ALL
of his sons,grandsons,gr grandsons, and so on, except for a few mutations 
that can and do occur. The import of that means that my DNA covers EVERY
descendant of Samuel Walker, male and female. What that really means that if I
find the common ancestor that I share with any or all of the other members
of Group 1, then I have found it for EVERY other descendant of Samuel.


Now some might wonder if I am truly a descendant of Samuel and not the son
of the milk man or was adopted. I finally found a known Samuel descendant,
Barry Walker, and he had his DNA tested. He and I matched on 66 of the 67 
possible markers currently being tested. This means that one of us had a 
mutation between my gr grandfather Sampson Walker and ourselves.


Now in a Walker subgroup you will find mutations in  0 to 4 markers among 
the members. The details can be found in the links presented on the main
page of my web site at

My DNA matches are at:
 FTDNA Lannie Walker DNA Matches
I am a perfect match to George Calvin Walker


I have constructed a chart showing the exact relationships of
Robert Darrel Walker, Harold Walker, George Calvin Walker, and 
Mary Sybil Morrow Hunt, along with the lineage of Robert Freeman Walker,
Charles Walker, and Lannie Walker (myself). See
 George_Lannie.htm
We just do not know exactly 
where we all link up but with the small numbr of mutations between us,
I am guessing that we all have our common ancestor at my Samuel's
brother, cousin, uncle or grandfather. North Carolina seems to be
indicated as the location where the common ancestor will be found, if
he ever is.


After the years that we have been communicating via emails and the two 
web sites related to the Walker DNA Group 1, we have come to feel like
real family. With dedicated Walker researchers like Leilani, Nan, and 
Corrinne, it just might go somewhere. I have been "just poking around 
in the genealogical bushes to see what pops out" and have had a few 
lucky breaks but I am not good at libraries and courthouses.
