I don't have a Thomas or Hazel.I do have Damron's that married into the Compton Family in 1837 in Pike County, Kentucky.
I don't have a Hulda Damron marrying a Thomas McCowan.I do, however, have a Hulda Damron marrying a Lewis Sturgill.I also have a Hulda J. Compton b. Abt. 1846 in Pike Co., KY (Mother--Alcie Elcy Damron and Father--Leander Lee Comton) marrying a Thomas McCowan b. 1844.
If any of this sounds familiar or helps, I'd be happy to share what I have.
