Johann Heinrich Knack (son of Wolff Heinrich Knack from Calbach and his wife Anna Dorothea) was baptized in Büdingen on 2 June 1746. Maria Magdalena Seitz (daughter of Ernst Peter Seitz) was born in Langen-Bergheim on 31 December 1742 and baptized in Eckartshausen on 4 January 1743. Johann Heinrich and Maria Magdalena married in Büdingen on 12 February 1767. The couple had two children, both born in Calbach and baptized in Büdingen: Johann Friedrich, born 27 March and baptized 31 March 1768; and Johannes, born 3 July 1770 and baptized 8 July 1770.
The family arrived in Russia on 17 July 1772. The Transport List notes that Magdalena gave birth to a daughter on 19 September 1772, and also notes that Johannes was buried on 14 August 1772.
