SYLVESTER HESCH BORN & DIED OCT 31 1915
1915? Could this be...? But no, it's not Anton and Elizabeth's missing child, because the twins were born in February 1915, and this grave is in the wrong (Pierz) cemetery.
So, whose child was this?
The only Hesch family in the area with the necessary space between kids was John and Ket.
Hmm...this'll go on my "needs looking up" list for the next time I go to St Josephs in Pierz .
