Not Everything has page numbers

Old documents usually have pages (except for tombstones), but they might not have page numbers.

Church records are especially notorious for this, especially in the days when records were kept in ledgers without printed forms. To keep track of where you got it, at least indicate the year of the record and what type of record it was (christenings, funerals, marriages, etc.). The name of the church and the location should also be included as a part of your source, but the year and type of record are essential to know where you got the information.
