Johann Martin and his family immigrated to Denmark (Schleswig-Holstein), departing from Altona, Duchy of Holstein, on 29 June 1761 under the leadership of Johann Thomas Gabler. They arrived in the city of Schleswig, Duchy of Schleswig, on 4 July 1761.
All of them lived in Denmark until 24 April 1765, when they immigrated to Russia. Johann Martin, his wife and the children Barbara, Elisabetha, & Georg Wendel arrived in the Volga German colony of Rosenheim on 15 March 1766. They are recorded there on the 1767 Census in Household No. 52.
Son Georg Wendel is still living in Rosenheim in 1798 where he is recorded on the census that year in Household No. Rm39.
