From the finding aid we don’t actually know which Penelope Bolling Clark Mr. Hartline meant, do we?
It’s impossible chronologically for Penelope Clark to have been a daughter of Colonel Robert Bolling, II & Ann Stith, she’s a contemporary (although I don’t know where the birth data on Geni comes from).
Penelope (unknown)
BIirth: August 14, 1684 New Kent County, Virginia Colony, Colonial America
Death: August 14, 1760 (76) Louisa County, Province of Virginia
Going up a generation, there’s only one known child of Jane Bolling so there’s not a Pocahontas descent here, that I can see.
Geographically it’s not much of a fit either.
Her mt DNA haplogroup is DNA Markers: H4a1, which is a group associated with England & Ireland. So there’s no native origins on her mothers side.
There’s no name affiliation (Penelope as a frequently appearing name in the Bolling family).
There are several origin discussions attached to Penelope profile for review.
