My Great grandmother Eva Poniatowska came to Northumberland form Slobodka, Suwalki Poland in 1899 to meet her brother Jozef. She was arranged to marry my great grandfather John Kolasinski that year. There are many Poniatowskis in this area and I am trying to find out how or if they are related in anyway. My great grandparents moved to New Jersey shortly after her arrival but, her brother Jozef stayed and raised his family there. I have many documents from Poland on many different Poniatowski groups but, I am having a hard time connecting them all. Any help would be great.
