I had no idea that the Spanish had any dealings that far north in America as early as the 1600's? Are their Spanish named towns in the Carolinas? Surnames?
The Spanish had a mission at Hopewell, Virginia!
DeSoto came as far North as Terre Haute, Indiana, while members of his party actually traveled all the way North to Lake Michigan. Then there's the fellow who put Spanish boundary markers in what is now West Virginia.
This was New Spain!
