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

Searching for family history, grandfather immigrated alone as a teen,had a brother or half brother named Adam. Left a large family behind. Died 1970 at age 72. Never spoke English so I knew very little of him. Any one out there from Pozen that knows of Prybylowski Family please respond. Thanks.
