Same with Yankees: some claim it comes from Jan-Kees, two Dutch names which can be
joined together. I do not know whether this is true.

Slightly off-topic (but still about Holland/The Netherlands)...
Does this fight in with radio commentator Paul Harvey's comment that that "Yankees" came
from the Dutch stereotyping their English neighbors as "John Cheese", due to the
large number of them with the first name of "John" and their large consumption
of cheese...then translating it into their language?

Just curious...

Hahaha, sounds pretty good! We like getting in a scrap with the English. I have no idea whether it is true, but it seems unlikely to me since the Dutch for Cheese is not Kees, but Kaas, and would be pronounced differently. Still, anything to annoy the English so once in a while...

The Dutch connection is probably true, but it is just a corruption of Jankin (diminutive of Jan). At least, that's what I read once. Etymology is worse than "forward looking statements" from OTCBB companies.
