David Roth, a farmer, his wife Eleonora, and son Johann Michael (age 5½) arrived from Lübeck at the port of Oranienbaum on 29 August 1766 aboard the ship Apollo under the command of Skipper Detlov Merberg. David Roth & Anna Eleonora Möbus had been married in 1765 in Büdingen, so this Johann Michael is not their son. He is believed to be Johann Michael Guttmann, probably a child from an earlier marriage of Anna Eleonora Möbus.
In 1788, Michael Guttmann moved from Kraft to Messer. He and his family are recorded on the 1798 census of Messer in Household No. Ms72.
