Looking for Zarembski, Czarnecka, Kowalski surnames

Hello! I recently learned that my ancestors from Poland were called
Mateusz Kowalski, who married Agnieszka Czarnecka. I believe Mateusz was from Brzozowka near Torun.
They had 6 children:
Heronim
Ireneusz
Piotr
Zacheusz
Helene
Maryanna.
Helene Kowalska was born in 1886 in Poland, then married Waclaw Zarembski in Pennsylvania, USA, when she was 25. From Helene's marriage certificate, Helene said she was from Brzozówka, Kuyavian-Pomeranian Voivodeship.

Any help is appreciated. My relatives traveled to Poland to find our family, but did not write out the stories before they forgot them, so I am seeking to document the history for the remaining family.

Thank you!

I don't know much about Zarembski name (besides the fact that it could have an alternative spelling in Polish, ie. Zarebski or Zarębski; some offices confused these spellings too).

My bf name is kowalski what is that one

Smith.

Aw that's cute thanks
