I've found that a lot of 'New worlders' will use various slang words specific to their ancestors even if only within their immediate family. A lot of Scots-Americans will say 'aye' without even knowing it

One such term I've heard in use in only two families is (and I've no idea of the correct spelling, so) hanyak, which is, as nearly as I can tell, a Scandanvian term about the equivalent yahoo (in the Jonathan Swift sense). Has anybody else ever heard of hanyak?
