Please note the correct spelling of Ed O'Kelley's name as follows:Edward Capehart O'Kelley (who was my g-g uncle).
As you probably know, Ed was the man who murdered Bob Ford after Ford murdered Jesse James.Ford's death occurred in a mining camp at Creede, Colorado, in 1892, for which Ed spent ten years in prison.He was released in 1902 and died in 1904 in the streets of Oklahoma City, Oklahoma in a gunfight with an officer of the law. I have written a book about Ed O'Kelley entitled "Ed O'Kelley: The Man Who Murdered Jesse James' Murderer."
I do not believe that Ed O'Kelley was ever married or that he fathered any children.I would be interested in learning more about the document you have and would look forward to hearing from you regarding your interest in this outlaw relative of mine!!
