Well, 10 years later I have a little bit more... Found LDS microfilms which showed my grandfather's birth in Nervi ( Sebastian Ernesto Ivaldi, 1907) son of Sebastian Guido Ivaldi(b,abt.1865) and Giuseppina Antonietta Spinetta. She is the daughter of Carlo Spinetta. He is the son of Andrea Ivaldi. Neither was born in Genova. They had several other children ( Carlo, Caterina(abt.1898)...) but not born in Genova-proper. I'm struggling to find where they came from. I've "heard" Ivaldi 's hailed from Ponzone area (about an hour north) and Spinetta might be coastal (like Camogli) But was wondering how far you got in the last decade?
