Hi, are you searching relatives in Italy? Almost everybody in Italy who has a surname as De lotto come from S.Vito di Cadore. I'm from there. I have a cusin living in NY his name is Romeo De Lotto. Who are you looking for? any De lotto has a family name that allows us to understand from wich family he comes from. In S.Vito there are 5.
My family name is Franthès or Francès (both spellings are right).
