Charles Arthur Adams, b 18 Jan 1885, LA; d 16 Feb 1940, McAllen, Hidalgo Co, TX; married; spouse Clara Belle Adams; father Charles Sanford Adams, b AL; mother Elizabeth Ward, b GA; residence Sullivan City; buried McAllen, TX; informant O.C. Adams, residence 1411 Gumwood, McAllen, TX.
Cause of death was oil rig accident.
I would look for his obituary, often survivors are listed and if he had any children they should show up. It would be interesting to learn about "O.C. Adams" the informant.
