I think I can help you if you need help, I live in NP where Buffalo Bill's house is, there is much info at his place which is open almost year round. There is also a historian that lives here that might be able to help, let me know if you need any help. My great uncle, Harvey Halligan stayed with Buffalo Bill when he was just a baby when his older brother died at a railroad crossing with a hay wagon. I have one great aunt left that might know something, I will try to remember to ask her, her name is Ethel McKain. My phone number is 308-534-2618, call if I can help in any way, Brad
