Wife Anna Margaretha Rupp Schwemmer, age 54, from Dobrinka, second wife
Child #1 Katharina Schwemmer, age 24, by deceased wife Katharina
Anna Margaretha's children by deceased husband Mr. Rupp:
Child #2 Johann Michael Rupp, age 20
Child #3 Elisabeth Rupp, age 30
I checked the 1767 Dobrinka census, of which I have a copy, and it appears that his name was Conrad/Konrad Rupp. He and his wife had at least one older child, Johann Christian, who was 9 months old when the 1767 census was taken in August of that year. This means the child's birth was likely in December of 1766, probably in Oranienbaum, Russia.
Head of the Household Conrad Rupp, age 22, Lutheran farmer from Darmstadt Seilzlas [?]
