I've been researching William Elba Stockton who married Ada Lily Benn. I believe he was the son of David Nickless Stockton and Lula Napper. The Stocktons moved from Hopkins County, TX and settled over the River in Sulpher Springs and Murray County and other locations in Oklahoma. There are numerous Deeds transferring land from Josiah Smith Stockton in Hopkins County, TX leading me to believe that Josiah Smith Stockton was his Father. I've traveled the country following the Stocktons. Hope this is of some use to you. Ada must have remarried after Elba's death to someone by the last name of Lansford. Do you know the name of this individual?
