Genealogy / Polish Gypsy Roots & Roma ancestors in their families [205]

I suspect that my ancestors may have been gypsy. Their name - Adamski - and their village of Cygany in southeast Poland was an area of gypsy camps. I'm just beginning my research by trying to determine if, indeed, my great-grandfather's first name was Ęrnie. If so, I need to know what its full name would have been. Any suggestions?
