This area was settled by Swedes, Norwegians and Germans. It's more or less a separate world in many, many ways.
We have our own jokes (
Ole &
Lena,
Sven &
Ole), our own words (Uffda), our own foods (lefse, lutefisk, knoephla), etc. So yah, most people would have no idea of stereotypes of "Swedish" or "Norwegian" names.
It's a good thing, though - you guys get to use good names without the baggage.
