My gt Uncle's wife died when the children were very young. When his daughter married; the name of her mother was actually the stepmother. Another instance was in the very bottom of the Marriage registration of my son n law's side; a notation was made with the gtgtgrandmother's real birth name(she was married in her grandparents surname)She had been adopted at age 4 it said with her siblings. Now that was a real find! So cheers for the registarions having extra notations. So Eyes Wide Open.....
