They appear to have been Hispanic ~ but so was this Cruz fellow who left the mission at Hopewell and came down the James to early Jamestown.
Remember, the King of Spain used to own the whole place. Settlement began in his time ~ lots of things were going on long before the English figured out how to settle abroad!
Heck, Spain “owned” most of Mexico, Central and South America. They pillaged and killed the indigenous Indians worst that the “white” Europeans. The Indians down there had whole cities and lots of gold. The American Indians just had land, no real material riches. The sold Manhattan for cheap beads. At least the “white” Europeans tried to compensate the American Indians for the land.
