her parents may be James Harvey Blackstone and Polly Shelley
can't find much except Ancestry trees
they have James as the son of James and Winifred Zachry but David Hughey on his profile for Blackstone/Zachry has their son James marrying Frances Rees. These profiles are all just gedcom downloads with no sources for anybody

Polly Shelley would be the granddaughter of Nathan Shelley which also has no sources

he had a son Isaac, not in wikitree
you might have to document the Blackstone/Zachry.
I tend to think James Harvey goes as a son of Blackstone/Zachry since that James was a son of Argyle and George Lee named a son James Argyle
