Family #20 in the 1767 Grimm census.
Johann Balzer is named in the Kulberg Reports as immigrating to Russia with his wife Anna. He was a Lutheran, a tailor from Darmstadt, traveling with document number 2393.  Also traveling with the couple were children Andreas, 21, Anna 18, Elisabeth 14, and Johann, 5. The family left Leubeck on the Pink Lev and arrived in Russia on 22 July 1766. 
Typically after arriving in Oranienbaum, the families took their oaths of allegiance and were settled in temporary housing barracks until the following spring, when groups set out for the Volga River colonies. At some point after their arrival in Russia but before the first Grimm census in 1767, Johann passed away.
At the time of the 1767 census, his wife is listed as a widow with only two of her children living with her, Johannes, age 6 years 6 months, and Elisabeth, age 15 years 5 months.
