I need help locating my great grandfathers history. His name was Michael Marconi. He married a woman by the name of Catherine. They had 4 children, Jerry, Salvatore, Joseph, and Angeline. They were in Brooklyn, NY. They showed up on a 1930 census. I believe Michael and Catherine were born and married in Italy. Jerry, Sal, and Joseph were also born in Itlay. Angeline was born in the states. I have been having trouble finding anything else besides what I have listed. Can anyone please help?
