| The purpose of this table is to graphically show the distribution of
shared and unshared SNPs within the Haplogroup I1 Northern Neck CORBINs.
So far, only four members of the family been BigY tested, and all four
are positive for A16956 and A16957, mutations that had to
have been acquired by at least their nearest common ancestor (John III),
if not further upstream.
SNPs in boldface indicate the person in whom the mutation took
place, except in the cases of A16956 and 16957, which may have occured
further upstream.
SNPs in the Kit# column are actual results of the tested individual.
SNPs in "ancestral" columns are logical deductions.
See further discussion, see below the table. |
| Although the paper connection of Isaiah CORBIN to Philip
CORBIN (#B81585, top row) is not absolutely proven, it is so highly probably
that, for the purposes of this table, I'm showing this connection. |

| It's unlikely that both mutations A16956 and A16957 happened
in the same individual. By testing a descendant of a brother of John
III (e.g., Rawley I), we can determine which mutations were present
in John II. Seven descendants of Rawley I are members of the project,
so please, some of you get BigY tested! I say, "some," because, ideally,
we would test descendants of Jeremiah, Thomas, and Ambrose (the three sons
of Rawley I whose descendants have already been STR tested). |
| The three tested descendants of James Madison are positive for A16959
(purple table cells) This mutation may have occurred in James Madison,
George, or John IV. We can begin to find out which by testing
a descendant of a brother of James Madison. If the brother's descendant
is negative, we have our answer: the mutation occurred in James Madison.
If the brother's descendant is positive, then we need to test a descendant
of a brother of George, and so on. |
| Only #621421 is positive for A16958, so the mutation can only
have appeared in him or his father because the other three descendants
of James Madison, including #621421's first cousin, were negative.
We can find out in whom the mutation took place by testing a brother of
#621421 or his father. |
