186x Grossliebental death records include the following entry:
Widmann, Johann, dod. 28 Sep 1869, Grossliebental, fa. Jacob Widmann, 1y 7m 16d, born in Duffinka
(Film #1884110/3 133).

The film of the birth record shows Johann's father as Jacob and mother Elisabetha Wagner.
The DOB fits in the 7-year gap between Elizabeth and Jacob S. Wiedmann.
The place of birth - Dufinka - cannot be located, but the records are found in the Grossliebental church records. At this time, Jakob and Elisabetha were living in Annental, which was a Grossliebental daughter colony.
The age in the death record indicates a DOB of 12 Feb 1868, which does not match the birth record, but these records are often inaccurate. The individuals are clearly the same.
