I too have been trying to find out where our Abreu geneology originated from. My Dad's paternal grand pather's names names were Severo Abreu and Carlita Abreu, I have no idea when they come to D.R. or how. They died during the 1920's His father's name was Santiago Abreu. My Daddy was told that his grandparents were from Spain, but that's the only thing we have on them.
