Karl Maul (age 20) and his brother Georg (age 7) settled in the Volga German colony of Norka. They are recorded there on the 1767 census: Karl in Household No. 6 with the Konrad Weigandt family and Georg in Household No. 8 with the Johannes Hamburger family.
Karl Maul may have arrived from Lübeck at the port of Oranienbaum on 9 August 1766 aboard the pink Slon under the command of Lieutenant Sergey Panov. The Oranienbaum passenger list records that this Karl Maul came from the German region of Isenburg.
Karl Maul, his wife Anna Margaretha, and children (Johann Heinrich, age 4; Anna Margaretha, age 1) are recorded on the 1775 census of Norka in Household No. 38 along with his mother-in-law Katharina Dörr.
