My great grandmother Theresa Iannaccone was from San Marco In Lamis, born in 1879. Her father was Vincenzo, and Marianna was her mother. She married Michele Accadia, and immigrated to Hamilton, Ontario, Canada in 1929. I believe she had a sister named Maria.
I have seen mention of a Vincenzo Iannaccone born there in 1891, who is a cousin of your ancestors. I am wondering if he might be a relative of Theresa?
