My Father and his family came from Russia to America in the early 1900s. My Grandfather was Shmuel (Samuel) We had always heard stories that prior to going to Russia, the had lived in Spain but left due to the anti-semitic persecution. That turned out to not be such a good idea.
I had heard that there is a town in southern spain where there are many people with the name Mazo but cannot recall the town. He had 5 sons, Max, Jack, Ben (my father),Herman and Nat.
