Family #104 in the 1798 Grimm census.
Johanna Schultz was born in Germany, but her family immigrated to Sarepta, Russia in 1765. Sarepta was a colony settled by Moravians from Saxony, Germany. Sarepta was attacked by the outlaw Pugachev in 1774, forcing the villagers to flee. The outlaws plundered the village's existing candle factory, hotel and church, and then destroyed the structures.
Johanna was only six years old when she was forced to flee from Sarepta. It could be that she an her family did not return, choosing to go instead to Grimm. If they did return to Sarepta, then she moved to Grimm as an adult.
She had an illegitimate daughter, Louisa. The name of her daughter's biological father is not given. It could be that Johanna left Sarepta when she became pregnant, and that the father of her baby was from Sarepta, not Grimm.
We don't have an exact death date for Johannes Happel's first wife, but based on the births of his children, it is likely that he married Johanna Schultz between 1793-1798. His first wife most likely passed away before 1793.
1798 Grimm Census 
Johanna Schultz Gapel/Happel does not appear in the 1834 census with the Happel family.  It could be that after the death of her husband, she remarried and lived in a different household. It is just as likely, however, that she was deceased. Had she survived, she would have been 76 years old.
