Harriett Tapscott |
We have already taken
a detailed look at Harriet, the apparent daughter of James and Elizabeth (Harriet and Harriott). But note that I use the adjective “apparent.” We need to examine Harriet further. But I warn you. This is exceedingly complicated and rather boring.Harriet was listed as
“m” (“mulatto”) in the 1860 census and as “W” (White) in the 1870 census. No
race was given for her in the 1850 census. When she died on 12 Aug 1871, her
death record listed her as “Colored.” All this is puzzling since Elizabeth and James
were both White, at least as far as we can tell. Perhaps Harriet’s race was inaccurately
concluded based on the race of her children, but might there have been other
reasons? Could her parentage be different than what we believe?
In Harriet’s death
register, Cordelia Tapscott, the informant, is named as Harriet’s mother, an
obvious error. Or is it? Could another Cordelia have been an unknown consort of
James and might Harriet have named one of her daughters after her mother? That
would explain a lot. Nevertheless, the only Cordelia Tapscott living at the
time, of which we are aware, was the child of Harriet. (Two Cordelia Tapscotts born
c1785 and c1814 and shown in a small number of online trees are easily proven fictional.) At
this point we need to continue our earlier look at DNA.
The following table contains
summaries of selected autosomal DNA matches for three people shown by paper
studies to be descendants of Harriet. For reasons of privacy, I am not naming these
individuals, who are the only Harriet descendants whose DNA test results I have
access to. (Thank you, One, Two, and Three.) Descendant One is believed to be a
descendant of only Harriet’s daughter Maria. Descendant Two is a descendant of
both of Harriet’s daughters, Maria and Cordelia, by two different lines. And
Descendant Three is a descendant of Cordelia, but also of Harriet’s
half-brother, Edmond, a child of Elizabeth Percifull by an unknown suitor. It
would, of course, be better for DNA interpretation to avoid a person with two
entirely different connections to Elizabeth, but one must use what one can get.
The table shows DNA matches between
the three descendants of Harriet with three different groups of people. The
first group consists of descendants of Henry the Immigrant through lines
believed to not involve James, son of Ezekiel Tapscott. The second is people
believed to be descendants of Elijah Percifull by routes that involve no
Fauquier County Tapscotts. And the third group is Fauquier County descendants
of Elizabeth, but not of Harriet. Shown are the number of matches and the average
shared DNA. The larger the centimorgan (cM) number, the closer the relationship.
I must admit that the data are questionable because analyses of the matches are based to a large extent on what others have entered into their trees. Nevertheless, the DNA results in the table
provide excellent evidence that Harriet was a child of James. The
three individuals tested show a total of 19 matches with descendants of Henry
the Immigrant, with a particularly large number (nine) for Edney Tapscott, grandfather
of Harriet’s father, James. This is very good evidence that James E. Tapscott was
Harriet’s father.
On the other hand, at first glance, the data provide only fair evidence that Harriet was a daughter of Elizabeth. There are matches to Percifull descendants, through both Fauquier Tapscott and non-Fauquier lines. Although this is what we
would expect if Harriet’s mother was Elizabeth, the evidence is shaky for two reasons. First, one would expect a greater number of matches. Second, a small, somewhat isolated, community, such as Cedar Grove and Turner's District in Fauquier Co, could result in endogamy or something similar. Multiple relationships might cause Percifull matches resulting from hidden connections, and this would decrease the already small number of meaningful Percifull matches.
But additional data strengthen
the conclusion that Harriet was a daughter of Elizabeth. We will start with a
member of the Holder line, a descendant of Robert Francis Tapscott, believed to
be a child of a Elizabeth Percifull and a person with the surname “Holder.” That
member of the Holder line has, as far as we know, no connections with other
Fauquier County Tapscotts than via Elizabeth. We find that the Holder
descendant has four matches with people
who are descendants of Harriet, but who have no other known connection with
Elizabeth. Three of these matches involve lines through both Maria and
Cordilla, but one involves only a single line through Cordelia to Harriet, for
which there is a match of 9 cM. The Holder descendant is separated from
Elizabeth by 5 steps, and the Cordelia descendant, by 6 steps. Thus, there are
13 degrees of separation between the two people descended from their most
recent common ancestor, Elizabeth. The Holder and Harriet descendants are fifth
cousins once removed. For 13 degrees of separation, we would expect the shared
DNA to be 6.64 cM, which is remarkably close to the 9 cM actually observed, considering
that the expected range is probably around 0 to 15 cM. Is this proof that Cordelia’s
grandmother and Harriet’s mother was Elizabeth Perciful? No. There are too many
things that could be wrong, particularly unknown multiple relationships. But it
is strong evidence.
The other three matches of the
Holder Descendant with individuals believed to be descended from Harriet through
both Maria and Cordelia show shared DNA of 39 cM, 35 cM, and 36 cM; however, it
is difficult to calculate how much shared DNA is expected when there are
multiple relationships. It is admitted, however, that these numbers appear
to be higher than expected, which would perhaps be around 13 cM, and that hints of unknown relationship
paths.
At this point we are going to say
that DNA evidence provides good evidence that Maria and Cordelia were, indeed, children
of Harriet and grandchildren of James Tapscott and Elizabeth Perciful. But that we
would like more data than what is now available.
Are you a Fauquier County
Tapscott (i.e., a descendant of Elizabeth Percifull, with or without the name “Tapscott”)?
Do you have DNA results (autosomal, mitochondrial, or yDNA) you could share? Sharing would certainly help our Fauquier County Tapscott research, and your identity
will not be divulged. If you have DNA test data on or transferrable to FamilyTreeDNA,
I encourage you to join the Tapscott Project. If you DNA data on Ancestry
or MyHeritage, please consider sharing them with me (see Ancestry Sharing or MyHeritage Collaboration). (And, of course, I would be quite willing to share my results with you in return, though you would probably find them rather uninformative.) If you have DNA data on GEDmatch, I encourage you to give me your kit number (again, I will do the same for you, if requested). And, finally, I urge males, particularly those with the name "Tapscott," to take a yDNA test and females to take a mitochondrial DNA test. Both tests are available at FamilyTreeDNA though, I admit, they are a rather pricey. (No, I do not get a cut.) To discuss using
your DNA test results in research, email me (address below) or leave a comment on this post. Thanks for your help, cousins.
