Family #37 in the 1767 Grimm census.
1767 Grimm Census 
Neither Johann Friedrich nor his mother are listed in the 1775 census with Kaspar Hepp. Most likely, the two were casualties of the early years in the Volga colonies. Both were deceased before the 1775 census was taken, giving his step-father the opportunity to remarry.
