According to the Eichhorn book, Melchior, three of his children from his first marriage (Johannes, Susanna Catharina, and Anna Susanna) his wife Anna Barbara, and two of their children (Hans Georg and Caspar) were in Denmark by 1762. Johann Melchior's older son Johann Ludwig, along with his wife Eva Margaretha and their two children (Susanna Catharina and Johann Jacob) were part of the same transport group.
