Metrical Books were the books that the Churches were required to keep as people were born, married and died. They are a super source of info even with some of the errors. It has opened doors to my familiy's history in Ukraine. Thee Mormon Church has microfilmed copies of MANY Eastern European Churches. Some years are missing, but I have gleaned a lot from this source. Any more ques, give a hollar. I am getting good in finding the films.
