Bierzunski Family 1. Open

I am looking for possible relatives of my Great-Grandmother, Malgorzata (Margaret) Bierzunska (Bierzunski). She was born in June 1886 near Lipno and was married as a teenager to a Wojciechowski. However, her husband died. We believe she sailed to America in either 1910 or 1911 and remarried. We know that she left her family of origian behind. She later brought a younger sister, Stephania (Stella, born 1894) to America. We believe there was at least one additional sister and possibly other siblings. Our records show that Malgorzata and Stephania’s father was Jan (John) Bierzunki or Biezunski and their mother was Izabela Grzymkowska or Grymkowska. We know that Malgorzata used to receive letters from family in Poland, but we do not know from whom. I’m hoping to reconnect family members after all these years. Thank you.
