Thank you for this information. Everything you say rhymes with some info I already have. BUT ... I have a note here that I have not verified and you have implied some insight into that. You say that your grandmother, Dollie Beard, was Manuels's third wife but I believe she may have been number four. Jean Samento was the first (verified), Op[al Eudora Ward was second (verified) and the third is Alice Mae McCain.
Harris County TX marriage records show Manuel C. Roberts (born about 1914) married Alice McCain on Mar 16 1949. She was born about 1928.
Al;so, I do have more information on Jean and Opal's children.
