My uncle was William Caraccia. I am sorry to inform you that he passed away in New Jersey about 10 years ago. He was born in New York City and the family was first in the ice and coal business and later heating oil. He married his first wife, whom I understand was of German descent and had one son with her. They divorced and he moved to Miami Florida and remarried. He is the son of Michael Caraccia and Martha Lepri Caraccia. He had 2 brothers (Frank, my father Steven) and 5 sisters (Catherine, Mary, Martha, Lucy and Margaret). Only Margaret is still alive. They all have children and grandchildren. I will do my best to verify your grandmothers name.
