(SOUNDS like N O A S O D) - Help with a Polish surname please

Good Morning:

I would be grateful if any of the forum readers know of a Polish/Ukrainian name that SOUNDS like N O A S O D or N O O A S S A U D if pronounced in a typical Canadian accent. I am looking for a relative from Ontario but don't know his surname. I think my father was a war baby who came and settled in Ontario after the second world war. Any suggestions on the name would be most helpful.

Big Thank You in advance.

How about: NASAD or NASÓD. These could be Polish, especially the first one ;)

More like Nowosad if Polish name - no Nasad / Nasód surnames found in Poland.

NASADA: this surname exists but is very rare and used by only a handful of people n Poland. Its meanings in older Polish included basis, settlement, or even an axe handle or rifle butt. Maybe some immigrant chopped off the final syllable to get Nasad???
