Scandanavian Brooklyn, that's funny. I think I've seen just about every ethnic group represented as being from Brooklyn/NY in a war movie except Scandanavians. I hate crepes, but I bot a crepe pan a few years back on sale just to make lefse.
The Scandanavians (Finns and Norwegians) came in the late 19th/early 20th century to work in the shipyards and as longshoreman. The originally settled in Red Hook and points south, but eventually made it down to the comparatively more prosperous environs of Bay Ridge, where a handful are still hanging on.
It was Finnish immigrants in Brooklyn that introduced the concept of cooperative housing to the United States.
