This is the most information I have ever read about the Arce's. There seems to be a lot of data about Arce's from Puerto Rico and Mexico. I am from Ecuador. I was in Spain and the Arce name is not as common as I thought. The American Arce's must be from one clan or family in Spain. It would be nice to go back a little further and find out where they all migrated from and if they are closely related.
