The other name for Galicia is, in fact, Carvajal. It's one of the three kingdoms founded by San Cho Noe I when he came from Cornwall to initiate the Reconquista.
It failed to last as a kingdom.
Several mariners named Carvajal worked with Christopher Columbus. One headed up the voyage that discovered Puerto Rico.
About half the officers on Magellan(McWallace)'s epic voyage around the world were also named Carvajal.
Today, most of the folks with that Surname live in South Florida. They used to live in Cuba. Before that they lived in Galicia. And as common as the name might seem, there are only a handful of them who show up in the record of passengers to the West Indies kept at St. Petersburg by the Spanish.
