My Grandmother's maiden name was Rocha. Her father and mother (Manuel & Ezilda Rocha), along with his brother Alexander and two of their children, Edward and Mary, emigrated from Portugal(somewhere in the Azores) and ended up in Hawaii. There are a lot of Rochas in Hawaii. Manuel also had two brothers named Ayres & Jose who stayed in Portugal. From what I know, there are Rochas from my family living in Madeira.
