My great-grandmother, Tilda M. Fulton, married a man named Thomas Lawson. They divorced on 05/29/10 in Oklahoma. She later married a man named Ira Claude Ditzler. I am trying to trace Thomas Lawson's ancestry. Any help or knowledge sharing would be very appreciated. They had a son, John (Johnnie), who was born of that marriage, but it was a little known fact and he was though to be another man's son. I have official divorce records, though. Thank you.
