My great-grandmother was Avelina Seara who married Jose Picon. Avelina lived until she was 99. She outlived my grandfather (their child) Delmiro Picon. I think she died around 1967 or so. My grandfather, Delmiro, had 3 older brothers. Offhand, I know two of them were Nicasio and Ricardo. I found out years later that Avelina had a child that was not Jose's (at the beginning of the marriage or just before marriage) that was given up for adoption or to the church. But, this child would not have been a Picon.
I'm not sure if you are from one of the brothers, or maybe a brother of Jose's. Do you have information that far back? I would be interested to know.
