Here's a record from 1897, found in the Baptismal Register at St Joseph's Church, Pierz, Minnesota.
This page is intriguing because, while it shows the child's father to be from OBERSCHLAG, BOHEMIA, we don't know who Martin Hesch was, or how he was related to Paul. Most likely a cousin?
Heinz wrote to remind me that Paul Hesch's GRANDFATHER was Martin, back in Oberschlagles! With German naming traditions, it'd make sense that this mystery Martin was probably a close relative. Not a brother to Paul, Mathias and Anton tho, because in the 1900 census, Marya said she'd had 5 children, and 3 were living. Hmm!
