We are descended from Marion Tidwell Horton and his first wife Mary Elizabeth Roe. But Mary Elizabeth died July 17, 1899 and Marion remarried (somewhere I think I have his second wife's name).
This is consisent with two property deeds that I found in the Commanche County courthouse.
Marion bought 80.75 acres on November 1, 1899. See that only his name is on the deed: M. T. Horton (no wife):

When  he sold the land December 5, 1900, his new wife is included as a grantor (but only by her initials "M. A"):
