My grandfater WL Goad, William Lawrence Goad, or Lawrence Goad is believed to have been a lawman in Oklahoma. That is family oral history. Now, all ancestors that might be able to give information have gone. Lawrence lived in Sallisaw in his last years. The 1930 census shows he was living in Redland then.

So here is the question. Since the family does not know where he might have been a lawman in Oklahoma, where might one looks for records of his service?

Thanks for any information.
