Are you still looking for your family? My grandfather also went by Pedro Catala Williams. He was born in PR but died in the Dominican Republic in 1992. His mother's name was Julia Williams and was of African-English descent. His father, whose name I do not know was Puerto Rican from Spanish descent. My grandfather had a sister has the same name as his mother. They got separated when they were little in PR. I know that my grandpa got marries many times and had a bunch of kids, all Catalas, but he was still marries to my granma when he passed.
