No Richard, I do not know when they settled in Atoka. They lived in Lehigh (which is now Coal County) for sometime. You can locate them on the 1910 and 1920 census that is online.
Remember, there were only three children that came to the Indian Terr. with them. (I think that is correct) Julina, Frank, and Charlie. Margarite married in TX. Alson Cornelius and Andrew Luke (my grandfather) were married in the Choctaw Nation. You would need to look up that information on the census. I can't remember off hand, and I don't have my Brothers Keeper program uploaded to my new computer.
