I am searching for the dates of birth and death for Robert Lee Stepp (born ca. 1878) and his wife, Isabelle Kelly (born ca. 1882). They were married in Union County, Mississippi on 17 October 1898 and later migrated to Texas. I think they first settled in Seminole, Texas but by 1930, the family was living in Witchita Falls, Texas. Any assistance would be greatly appreciated.
