Johann Ludwig Müller, a single cobbler (Schuhmacher), settled in the Volga German colony of Kratzke on 7 August 1766. He is recorded there on the 1767 census in Household No. 35.
In 1788, Johann Christoph, Georg Franz, and Christina Dorothea Müller moved from Kratzke to Frank. These are believed to be Johann Ludwig's children.
The 1767 census records that Johann Ludwig Müller came from Saarbrücken in Nassau.
