Hi Amanda. I am also a Grimaldo with Mexican-American heritage. I am quite pleased to see so many with the Grimaldo name around. I have been told that the name is of Spanish decent and the in Spain it is as common as Smith or Jones is in the U.S. I am very interested in finding any other Grimaldos who may descend from Daniel Aquirre Grimaldo.
By the way there are several of the Grimaldo clan residing in Michigan
