There appears to be two Wild “Bill” Cody’s one, William Cody, died penniless at his sister’s home in Denver in 1910 and Samuel “Wild Bill” Cody “probably born Franklin Cowdery in Iowa” who died in a plane crash in 1913.
I wonder if the latter took the formers name as a gimmick, though it appears that his Wild West show didn’t run for long, and wasn’t as noted as the original Wild Bill.
A bit of trivia :- William Cody, was a direct decendant of Phillip Le Cody originally Le Caudey from Jersey, so now you know.
