I have a question. My grandmother was married once before while in Italy and migrated here with her first husband. Something happened with the first marriage and a few years later she married my grandfather. Im trying to figure out if her first husband died, or he left her or she left or something. I ask this because her whole life she signed her name with her maiden name, then first marriage surname, then my grandfathers surname.She signs it with 3 last names! I have a paper from a month before she died and still then she used both marriage surnames. I find that odd and was wondering if that is Italian etiquette.Here ,when one marriage ends the surname is replaced with the new husbands name. Ive never seen this before. Its been suggested that maybe she never married my grandfather because she was still technically married to the first one and maybe she just took my grandfathers name. Any speculations?
