I'm the registrar for my DAR chapter here in Texas. They would consider the census records since the family lived with Adelia's parents after she was married to Samuel Boyd.
When I received the death certificates I had requested from Austin, I called to tell them about the mistake on Robert Boyd's. She said if I could get other records (marrige of Adelia and Sam or death cert of Adelia naming her husband), along with the census records, they would change it since my great aunt was the one who gave the wrong info and has already passed away.
It would make the DAR happier too. I could even send a tombstone to the DAR if it shows she is the wife of Sam Boyd. I know her parents are buried at Antioch cemetery but I can't find her on any burial lists from here.
Family Bible records would work too and I feel sure Minerva Ann Glasscock had one but there is no knowledge of where it might be.
