Don't know if that is true or not, but there are an awful lot of people with native blood and not that many with English surnames!
Pirates had women. Actually, they may have had quite a substantial settlement in Maryland in the early 1600s. A partial "census" revealed up to 20,000 Europeans there as the struggling English colony of Jametown got into business.
BTW, about 90% of the early immigrants to Jamestown died of disease. There's a hill there with 60,000 burials from that period.
That's only marginally better than the Indian survival rate from the same diseases and conditions.
A Spaniard named Cruz kept a diary of his life in Jamestown. He'd earlier been at the Spanish settlement on the James River, and when that town closed down he moved to Jamestown (and became an Episcopal and settled there).
His situation was considered quite normal. As we recall all the Protestants in Europe were, at that time, working with the Spanish to stop the Turks from taking the Balkans, and moving into Austria. They were all buddy-buddy.
Even John Smith had been a POW under the Turks. then they held the 30 years war and that reshuffled the decks.
