Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

Merged: last name Nyc

I'm hoping someone can help me. I am trying to help my grandmother find an answer to something that has puzzled her for years. her family emigrated to the USA in the late 1800s, and she hasn't had any success in finding information on her heritage. her family surname is Nyc. can anyone help me with any information about her name? Anything would be helpful!
