My grandfather, Thomas Duggan was born in TN in 1884, and married in OK in 1909. He moved from TN with his mother, Mary Ida, I do not know why. He had a son, George, born in OK. The other names are unfamilier to me. If you have any other questions or Duggan names I will gladly compare and help if I can. There could be a connection and that would explain why the family moved to OK. I do not know if they lived in Indian territory.
