Thank you, Linda, this is very helpful.I have been looking for an abstract of James' will, and I don't know how I missed Carol's post. It's just been in the last couple of months that I have turned my attention to Peter rather John b. 1780 as William's father. So that's why I may have missed it earlier.
This Peter being a minor when James died is a good hint to his age.
The Bedford and Franklin Bushes, descended from John b. 1780, are more than likely also descended from Abraham and Isaac of Lancaster. An earlier John in Bedford was the uncle of Capt. Billy Bush of Boonesborough. He had only one son, Phillip, who also went to KY.
Do you know who is Alice Riveer's father? She is likely not a sister of Peter who married Hannah Bush, since Peter is not named in the suit where I found that Alice had siblings Thomas, Elizabeth, Sarah, and another sister who married a Hayden. Unless Peter Riveer was deceased in 1846 and had no children.
