Hmmm..I don't know if anyone can figure this out! But I've got Robert Woodson Fitzgerald, b. 1778 in Amherst, VA, the son of Bartlett H. Fitzgerald b. 1759 in Amherst. I looked through all my records and I don't have any of the same names as yours other than the possible connection between Woodson Robert Fitzgerald and Robert Woodson Fitzgerald. I wish I could be more helpful but I can't find a Philander or any of his other offspring. Sorry. What are you using as a source?
