I am trying to find information on my father Attilio Villa. I am planning a trip to Italy in 18 months and would like to find out how to research and locate where he is from and any family I might have there. My birth certificate says he is from Stiesti, one of my sisters' says Monticello and one of my brothers' says Staitie. We cannot find his name on any passenger list and am told he came through Niagra Falls from Canada.
