There's not much to go on, frankly.There's some question as to whether his real name was Brocius.Some people think it may have been Graham.
There are a couple of claims that he came from Indiana.One says that he was from Crawfordsville and after the Civil War he abandoned his family and went West.The other says he was from Wayne County, but there are few details.
After some problems in Texas and New Mexico, Curly Bill showed up in Tombstone in the late 1870s.He was called one of the leaders of the cowboy faction, but even that is debateable.
Wyatt Earp claimed that he killed Curly at Iron Springs, AZ in 1882 during the legendary/notorious Vendetta Ride.If so, Bill's body was taken away from the site and buried in an unknown location.
Other cowboys said the Iron Springs fight never occurred and that Bill headed into Mexico to escape the Earps.If that was the case, no-one is quite sure what happened to him.
Curly Bill is one of the real mystery figures in the Old West.Outside of that period 1875 to 1882, almost nothing is certain.Researchers keep looking...but nothing concrete at this point.
