Have you tried divorce papers for Thos/Opal? On Thos' DC he says he was widowed, so maybe he didn't think he was divorced. LOL Apparently, she was also divorced from HEWITT, when she died. I found several articles naming folks in the explosion, but no obit for Thos or Opal that I could find.These obits would give you the names of the surviving ch, hopefully. Check with local library....obits might be in Fannin Co, since this is were they were from, and buried.
