We have a letter. We found it with my grandmother stuff when she passed away. It has some really awesome facts about Jessie James. I have not researched this very much, so I don't know what any letters look like. I found it interesting the letter matched the exact dates on a headstone, and and some of the symbols are interesting too. it is post marked and dated. We do have some pics of frank and jessie james with two other brothers. We had or have the original, but my mom either lost it or something, as I am 5th or 6th cousin, I know through my aunt sally. This is documented. It mentions a photo album.
