Hmm. Perhaps it should read: “When Judith Ursula Fleming was born in 1610 in Cumbernauld, Dunbartonshire, Scotland, her father, Sir John Fleming, 1st Earl of Wigton, was 43 and her mother, Countess Lillias Graham, was dead.”
Deceased mothers at time of birth is quite commonplace in whatever dimension the Family Search tree exists. In our universe these things rarely happen, I find.
Why has she got two names?
How (& when) did she get to Virginia?
What reliable supporting evidence exists for her in either place?
Also, the husband - John Banaster Tarleton (two names again.) Made me think of Banastre Tarleton. Coincidence, or fishy? Is there any reliable evidence for his full name? Supporting documents etc?
As for the dna, (whatever this may be, and I’m guessing someone’s added their results to a tree on Ancestry with Judith Ursula Fleming in it.) It could prove you were related to the test-taker (which wouldn’t be a surprise), but it wouldn’t prove the tree they had attached their test results to is correct, unless that tree is supported by reliable sources.
