I am trying to find more about Giacomo Costa Zana and Maddalena Pastor Ris who had a son Carlo Costa Zana on 4/2/1902 in Cuceglio, Torino, Italy. Their marriage records may reflect information on their parents/families. I assume they married in the same area no later than 1901. I do not know of any siblings of Carlo (and would love this info also). He married Effisia Quillico in the USA around 1921. Any help is most appreciated.
I want to reduce this request to just finding out about Giacomo Costa (Costa Zana). The only concrete reference I have to Carlo's family is on the manifest when he arrived in the USA in 1920, and he listed his father as "Giacomo Costa ana Cuceglio".
