In various records the wife of Richard Woolfolk (son of Robert & Ann George) has been listed as married to Sarah Taylor, thought to have been a sister to Pres. Taylor (I have never seen proof of this fact). I noted your web page has her listed instead as a dau of Pres. Taylor. The following info you have posted would indicate more research needed in this area:
Richard Woolfolkb 1763 married Sarah Taylorm 1792(dau of Pres.Taylor)
Published bio records show the following. Pres. Zachary Taylor was b 11/24/1784 in Orange Co., VA.
This would indicate, if Sarah Taylor was indeed related to Pres. Taylor, it would be as a sibling rather than dau.
Perhaps someone can furnish more info on this subject.
