Are you familiar with Mary Anne Randolph Custis, granddaughter of George Washington, and who married General Robert E. Lee? They lived in Virginia at that time. I don't think that she is the one you are looking for, but perhaps a relative of hers. I am trying to locate her Custis relatives lines, as a family tale says we are related to her by siblings or cousins. If you need more info on Lee's wife and their kids, go to the Robert E Lee web page about his house in Va. Let me know if I can be of any help and if this turns out to be the right line.
