He immigrated first to Denmark (Schleswig-Holstein) where he settled in the colony of Veltenhof. He married on 26 May 1760 in Fredericia, Denmark, to Anna Barbara Albrecht. She had been born in Heiligkreutz near Odenwald (northeast of Schriesheim) on 1 May 1741.
They immigrated in 1763 to Russia, arriving in the colony of Anton on 7 September 1764 along with Anna Barbara's brother and his family. They are listed on the 1767 Census of Anton in Household No. 11.
