I believe there is a
Church Slavonic language and in places Polish.
There is an alphabet in the
Polish version.
There was a couple: Roman Staszyna and his wife Maria, e.g., circa 1732 - there is a baptismal certificate for their daughter Maria, entry six on the left card:

It is written: daughter of ~"Романа Сташины и жены его Марии".
And here is the couple, 2 times:

Entry 8 on the left card and entry 2 on the right card.
I was under the impression that the cards/scans/entries were not in sequence.
