Friedrich Asmus, a farmer, immigrated to Denmark (Schleswig-Holstein) in 1762. He joined the migration to Russia and settled in the Volga German colony of Holstein on 24 June 1765. He is recorded there on the 1767 census in Household No. 16 along with his family and a note that they relocated to the colony of Dobrinka in 1768.
In 1788, Friedrich Asmus and his family moved from Holstein to Grimm.
