No, I don't have the will of William Lee but would sure like the citation. I think I found what little information I have on my Brooks/Lee connection in a book on the Lee family about 10 years ago.I think that's the source of Ann Lee's maiden name - so I can't vouch for it.
As for the Floyds, not only did Susannah Lee marry Enoch Floyd in Madison County, KY, Garland Ray married Elitha Floyd in Edmonson County, KY in 1869 after his first wife Sarah Lee (Susannah's sister) died in 1868 in Warren County, IL.They returned to Warren County IL where they died and are buried.
There are some postings in the Gentry family forum that might help you with Enoch Gentry's father. If he was an Estill County KY Gentry, one poster says that they are descended from Nicholas II son of the immigrant Nicholas I.
