I'm trying to straighten out the ancestry of a Martha Washington who married Robert Randall. Her tombstone here: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=34... says that she was born 1762 and the daughter of James Washington & Catherine of Westmoreland VA.

Several Google Books references say that James is the son of Lawrence, who's the son of John, who's a brother of (the) George Washington. But the dates don't add up and may not even be possible. Does anyone know what the actual line is here?
