Gryczko/Stankiewicz Family

My grandfather Michael Gryczko (born Pawel) came over from Poland in 1910 and my grandmother came over in 1911 along with my aunt Anna and my dad Charles (born Czeslaw). My grandfather was born in Czostkow, Suwalki, Poland and my grandmother was born in Huta, Fllipow, Suwalki, Poland. They lived in Glen Cove, New York until about 1919 when they moved to Bayonne, New Jersey. I know there were other families with the same last name. I know that name appears in many other states. So my main goal is to determine if there were other relatives related to my grandparents. Any information would be greatly appreciated.
