We now have 76
men included in this Lineage by testing - representing more than
30 separate families. (1000s more are
indicated, as each tested man represents his paternal line -
which is his father's father's ... father's male line and all of
these men's son lines ). We include a handful of men with
other surnames. Two of these men knew that their heritage
was Barton, one was adopted at birth and knew nothing of his
heritage and the others are working to understand how their
Barton genetic ancestry emerged in their surname.
We are a part
of Haplogroup R1b - the most common in Europe. Our
ancestors (according to
National Geographic's "Early Man Migration")
See the
National Genographic site for their incredibly detailed
story of the migration of man.

General information about our
Haplogroup R1b
|
About 40% of all men who
trace their origins to Europe are R1b |
|
Proportions of R1b in the
European populations increase as you move from east to
west |
|
Haplogroup R1b is defined
by a genetic marker, M343 - which first appeared about
35,000 years ago |
|
Based on
a formal test (called a "SNP" test) of several of our men, we
are sub-classified as R1b1c |
|
R1b1c
Haplogroup Description from Family Tree DNA --
believed to have expanded throughout
Europe as humans re-colonized after the last glacial maximum
10-12 thousand years ago |
General comments about our
Lineage I
|
Our paper trails ending in the
1600s & 1700s are only found thus far in Lancashire and
the southern USA |
|
Our Barton Lineage I has
no close matches with other surname families at 37
markers |
|
We are most
distinguishable by our 14-10 at marker DYS385 - where most
R1b's are 14-11 |
|
We also are different from
the most common R1b marker results at DYS464c, DYS456,
DYS576 and CDYa/b |
We can begin
to see "branching" in our Barton Lineage I by small differences
called "mutations". When these mutations are shared by
some men and not others, we theorize that these were inherited
from a shared common ancestor.
We identify a
branching in our Lineage I by our results at CDYb
|
Through
our paper trails, we know that this mutation occurred no
later than the 1620s |
|
Group
CDYb=36 has 61 men. We call this the "Colonial" group,
based on 1600s paper trails to colonial VA & MD
|
|
Group
CDYb=37 has 15 men. We call this the "Lancashire"
group, based on a 1600s paper trail to Lancashire
|
|
CDYb=37
men whose paper trails end in the Southern US are believed to not descend from the Colonial VA & MD
families, but to have immigrated separately
|
We have
identified a number of family branches through shared mutations:
|
The Colonial MD family
appears to be identified by a 12 at DYS444. More
testing is required to verify |
|
The Colonial VA family
appears to be identified by a lack of any defining mutation.
This is an unsatisfactory definer - and it is hoped to be a
temporary situation. We will have to test more markers
to find an identifier for this family |
|
The
"Thomas m Elizabeth Ward" branch of the MD family and a
number of later families share a 12 at DYS391
|
|
The
"Henry, b1793" family shares a 12 at Y-GATA-H4
|
|
The
"Bavestor" & "David m Elizabeth McCormack" families share a
14 at DYS393 |
|
The John,
b c1737 Randolph Co NC family and two men surnamed Eskew
share a 16 at DYS570 |
|
The
"Willoughby m Sarah West" family is identified by a 18 at
DYS557.
|
|
A branch
of the "David m Ruth Oldham" family has two distinguishing
mutations - a 13 at DYS388 and a 11 at DYS452.
Origins of both mutations are confirmed to living men, so
this branch information is of limited use.
|
We have also
identified some possible branches, which need additional testing
to confirm
|
Shared 18s
on DYS576 for A-38 & F-4 |
|
Shared 36s
on CDYa for B-39 & B-16 |
|
Shared 12s
on DYS461 for D-11 & D-16 |
|
Shared 16s
on DYS557 for B-28 & D-03 |
|
Shared 18
at DYS557 for A-47 with D-11 & F-11 |
There are a
few shared mutations that paper trails & other mutations suggest
are random matches - instead of shared mutations. Further
testing would probably confirm this - but isn't recommended.
We are ignoring these.
|
Shared 30s
on DYS449 for A-43 and A-16 |
|
Shared 18s
on DYS576 for B-39 with A-38 & F-4 |
|
Shared 16s
on DYS557 for B-28 and A-43 |
|
Shared 12s
on Y-GATA-A10 for B-39 and A-43 |
Based on the
initial results from the newest markers at FTDNA, upgrades to 67
markers is encouraged for the following:
|
A-38 & F-4
to confirm their shared 18s on DYS576 indicate a recent
common ancestor |
|
B-39 &
B-16 to confirm their shared 36s on CDYa indicate a recent
common ancestor |
|
D-11 &
D-16 to confirm their shared 12s on DYS461 indicate a recent
common ancestor |
|
B-35 to
confirm mutations in B-28 |
|
One of the
men of the Henry, b1793 family to see if they link to the MD
family |
|
A-17 to
confirm the 24 on DYS481 represents Bavestor
|
|
B-07 to
confirm the 14 on DYS446 represents Moses
|
|
X-1 to
confirm a shared ancestor with A-17 & B-15
|
|
Any or all
of C-02, C-16, A-37, A-20, A-21, C-07, F-12 to confirm the
12 at DYS444 is the defining marker for the MD family |
|
Any of
A-28, A-49, A-04 to confirm the 18 at DYS557 for Thomas m
Sarah Wilson |
|
D-16,
B-13, B-05, C-06, B-31 to determine which branch of CDYb and
other branches (requires 37 marker test) |
|
A-47, A-16
to determine if they match a branch emerging in the latest
markers |
Testing was done at
DNA Fingerprint (now a part of Family Tree DNA) on a limited group of
10 men. Only 2 mutations were found across 30 additional markers
and both appear to be recent. There has been no further
exploration of this possibility.
