Thank you for your response. So Zofia is not the sister of Franciszka. Franciszka parents are Walenty Bakalarczyk and Michalina Pol. It may be a cousin.
No I don't have any information on Maciej and Apolonia. Who are they?
My sister-in-law asked me to search for her family. Her grandmother came from Praszka parish and her 3 x great-grandmother Antonina Bakalarczyk married Józef Zając in 1838.
Antonina's parents were Maciej Bakalarczyk and Apolonia Krzak.
