My Grandmother's maiden name was Wilson and Bill Wilson was her great uncle. She gave me the book she had about him (Bushwhacker) when I was around 10 (1962). She was a little embarrassed at the time, mostly because my Grandfather (b.1876) teased her about having an "outlaw" as a relative. I think mostly it was because his father (b.1845) served in the union army as a young man. She was also related (great uncle x 2,3 ?) to James Wilson, one of the signers of the Declaration of Independence. My Grandfather also gave her grief for this also, since he was a politician he was naturally a "polecat".
