Genealogy / looking for information on my grandma's family "Lugoski". [5]

My Grandmother is getting up in age, and it has been a secret wish of hers to visit Poland before she dies. So, as part of a gift before we take her, we're trying to find out information on her family name. Is there any information on the name Lugoski? Like, what does it mean, whats its crest, etc? Any information would be much appreciated.
