I once knew a guy with the surname of Halluska. This is a very unusual-sounding name. I really can’t imagine what language it could come from. I’ve been unable to convincingly link the name, through various searches, with German or any other Northern European language, and it certainly doesn’t sound French or Italian, nor Greek.
Both the Halluskas I knew were very Northern European-looking.
My only guess is that the name is Basque or Hungarian. Does this sound reasonable?
Looks Czech or Slovak to me. Haluska (one “l”) are a type of noodle. In Hungarian, they’re known as galuska (the “g” -> “h” transformation in Czech or Slovak is very common.) In German, the same noodles are known as spaetzle.
Anyhow, that’s what I see. It may very well be a false cognate.
