Did you know that Billy the Kid's real name is William Bonney?
Black Bart - Charles E. Boles
Calamity Jane - Martha Jane Canary
Kit Carson - Christopher Houston Carson
Butch Cassidy - Robert Leroy Parker
Buffalo Bill Cody - William Fredrick Cody
Wild Bill Hickok - James Butler Hickok
Belle Starr - Myra Belle Shirley
Annie Oakley - Phoebe Ann Moses
And, Doc Holliday - John Henry Holliday
I can see how some of these people would accept a name change that seems more in line with them. And they all have a certain " ring" to them.
So, now you know!
