My great grandmother Rosina DiNatale had a half brother named Rosario - I do not know who he married. Rosario had a sister Angelina and then several half brothers & sisters. Rosario's father is Salvatore DiNatale born May 2, 1844 and died May 2, 1918. His mother is Carolina LaPorta (first wife). He then remarried and had my great grandmother. They all lived in Piazza Armenia is Sicily, before coming to NYC areas.

Does this sound like your guy?
