I've attached a one page jpeg file that supposedly is written in Russian and is from a church in what is now the southwest Ukraine. I am starting from scratch here so. Is this a page of births (baptisms)? I believe this is from the month of April. If so, are the third and fourth columns the birth and baptism dates? what is the next column heading and what is written in the column for each entry? For example, are these the first names given to a child or are they the family last names? And last, what is written in the last larger column?

the surname I am looking for is pronounced Savko or Salko or, at ellis island, written Szanka.
