Juliana Fett and Johann Henrich Pirmann
Juliana Fett and Johann Henrich Pirmann married in Freinsheim 12 Feb 1777. He was the son of Maria Christina Apresch and Johann Reichart Pirmann born 23 Apr 1749. I wasn't able to find a birth record for Juliana.
Juliana and Johann Henrich had four children, all christened in Freinsheim:
I don't have any further definitive information on this family. Certainly Hennrich Adam and/or Johann Philipp may have been the fathers of children born under the name Pirmann during the records gap between October 1798 and 1815.
Johann Philipp may or may not be the Johann Philipp Pirmann who married Anna Maria Wieser in Bad Dürkheim 24 Jun 1818. He's almost certainly too young to be the Johann Philipp Pirmann described in the 1828 legal agreement that probably refers instead to his uncle Johann Philipp.
Juliana Elisabetha is one of two possibilities for the Juliana Pirmann who married Georg Jacob Stocke, but I wouldn't say that she's the stronger possibility because she would have been six years older than her groom.
