> Could a random village have a black resident, maybe a sailor or member of a trade expedition that happened to settle there? Absolutely.

No, because they would have died from the novel diseases the village would have had. There's a reason why when Europeans went anywhere they died by the boat load and pretty much everyone they brought back to Europe also died.

It's always fun to remember that Pocahontas died in England after being there less than a year.

“When Yasuke was presented to Oda Nobunaga, the Japanese daimyō thought that his skin must have been colored with black ink. Nobunaga had him strip from the waist up and made him scrub his skin.[22] These events are recorded in a 1581 letter of the Jesuit Luís Fróis to Lourenço Mexia, and in the 1582 Annual Report of the Jesuit Mission in Japan, also by Fróis. These were published in Cartas que os padres e irmãos da Companhia de Jesus escreverão dos reynos de Japão e China II (1598), normally known simply as Cartas.[23][24] When Nobunaga realized that the African's skin was indeed black, he took an interest in him.”

You both seem in agreement actually.
