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

I don't know if it spelled right. But my Father said our name in polish is "jazgracz". I can only go back to my Grandfather when I search for this name. I can only trace my family back to around 1920. They lived in Shomkin, Penna.

The only word I found in Polish that is close to it is a word for a fish.
The english spelling of the name is Yesgosh
