He must have been a very intelligent and determined man. Not only did he assimilate into a completely foreign culture and marry into their aristocracy, but he did so after starting as a slave of said culture.
While this “going native” is interesting, sadly there are not much accounts of his whereabouts.<p>This reminds me about the concept created by the Spanish writer Miguel de Unamuno: “intrahistoria”, i.e. the unofficial history formed the common people.
Loyalty is one of the strongest qualities of Spaniards. Or curses. Depends on the occasion I guess. But the saying "ser más papista que el papa" (to be more pro-pope than the pope himself) is not said by chance in Spain.
Talk about turning your luck around...<p>Somehow not mentioned in the Wiki page, but <i>Guerrero</i> actually means Warrior in Spanish. So I get the last name comes from him (?), unverifiable of course.<p>EDIT: Several people pointed out that the surname “Guerrero” has existed in Spain long before the 1500s, so my guess about it originating with Gonzalo Guerrero was off. Thanks for the corrections—leaving the rest of my comment for context.
