looking for the bucka family

hi im looking for the buckha, bucko ,bucka family

my great great grandma was mary bucka she was married to john sadanowicz (my great great grandpa) she migrated to canada with john then passed the border with john to united states. her daughter is genevive sadanowicz. i believe her and john married in poland but im not sure all i know is that they met there.

also,
noone knew for sure how to spell her last name on the things i found of ancestory.com it was spelled buckho but on my great grandmas birth certificite (cant spell) it was bucko and on my great great grandmas death certificite it was spelled bucka.

If it was Bucka then it was the feminine form of the adjectival surname Bucki (because adjetcives must agree with the words they modify).
But it could have been a noun-based name such as Bućka, Bućko, maybe even Buciek, Buczek, Buczka or Buczko.
You would have to determine the real spelling as shown in Old World (not American) documents.
