The mother attached to Sarah died in 1656 and Sarah wasn't born until 1676. So either the dates on her mother are incorrect or she's connected to the wrong parents.
She's my son's paternal direct ancestors and I don't have any parents for her in our tree, but other Ancestry trees have her parents as:
Father Edward Thomas Elliott
Birth
1664 • Virginia, United States
Death
17 Nov 1716
Mother Sarah Armistead
1660 • Gloucester, Gloucester, Virginia
Death
1720 • Perry, Indiana, United States
I haven't validated that those are her parents either though, that Indian connection throws me since everything else in the family seems to be rooted in Virginia.
Bottom line, I don't know that anyone knows who her parents actually were, but t couldn't have been a woman who died before she was born.
