I don't think I have a true connection for you. None of the folks you mention fit into my current files. However, I do know of a branch of my GADDIS family that ended up in Oklahoma. Is Depew, Creek County, OK anywhere near Norman, OK? The only reason I ask is that I have a Jesse (which most folks would pronounce Jessie) Roy GADDIS in my files. He died in Depew, Oklahoma. It might also be helpful to know what time frame you're working with. Let me know if there is anything I can do to help or if you think there might be some connection.
