Bialecki Family

[clapton]

Hello to everyone, greetings from England.
I am hoping the someone maybe able to help me?
I am trying to research my mother's family tree from Poland.
I am looking for my grandmother's family, her parents and siblings.
I have Cacilie Geppert geb Bialecki born 13.10.1900, Chojno Kr. Rawitsch.
Her father was Johannus or Johannes Bialecki bn? and mother was Antonina Tyzler or Tysler bn in 1873.
My grandmother married Johann Karl Geppert who was born 15.1.1889 in Korsenz/Militsch.
His parents were Friedrich Carl Geppert and Malgorzata Konieczna bn 1860.
Kind Regards,
Irene Cooper
