There are no books from the Berznyk church from 1866 to 1877. I can't find Michael's birth. Who is Petras Klimčiauskas? In the village of Forest there were several Families Klimčiauskas I think it could be this Michael Klem
Aruna
Michael's father could be this
Simonas Klimčiau
But not appropriate, the mother's maiden name, maybe a mistake in the wedding record.
