The Dunnam's you mentioned don't sound familiar. My Grandfather was Thomas E. Dunnam lived in Greene Co, AR his wife was Leffie A. Guest, Grandad's father was James M Dunnam norn 25 Jan 1871 died about 1903. married Ida Ella Jones, after James died Ida married Harvey Newton Adams, my father has so much info on this family it will take me a lifetime to sort it out. I want to get him a Gen. package for his computer and talk him into getting on line. Don't know if our families are connected but maybe. Name of the town Tyronza is one i reconize at all do you know what county it is in? Are you from AR? Don't know if this helps but if it does and I can be of any help let me know.
