My grandfather, Ubaldo, came to the U.S. in 1911, returned to Italy for WWI and then, emigrated permanently in 1920s. We were always told that he had younger half-brothers who he sent money to so that they could come to the U.S. and instead they went to Argentina. Their father's name was Bartolomeo. We know that he had a brother Raffaele and a sister, Addolorata. I do not know the names of the younger half-brothers who went to Argentina.
