This story's been around awhile, but I've just studied it in depth for the first time. You were taught in school, of course, that America was named after a Welshman, Richard Amerike (or in Welsh, ap Meryk), who was the patron of a Genoan sailor, Giovanni Cabatto ("John Cabot"), who in1497 sailed from England to what he called "New Found Land." No? Or that the Stars and Stripes of the U.S. flag were based on the coat of arms of the Amerike family? Here's the BBC's version.
What I found interesting is that I could find no one in the United States census records named "Amerike" or "ap Meryk." I found eleven persons named "Meryk" in the immigration records; they were all German or Austrian, except one who was from Poland. I found eight persons named "Meryke"; again, all were German except one who was Polish.
