This is an older post, so I am not sure if you will get this reply.
My Grandmother was a Morales. Her Family immigrated to Hawaii from Puerto Rico between 1921-1923.
My Grandfather was Rodrrigues/Rodriguez. His Father was born illegitimate in Puerto Rico with the surname Acevedo and legally changed it to Rodriguez in 1945. Half the Family uses the proper Spanish spelling, the other half uses the Portuguese spelling. They immigrated with the first wave from Puerto Rico, between 1900 and 1901.
