Widow Anna Margaretha Pfeifer, a farmer's wife, and her sons (Johannes, age 19; Johann Lukas, age 18) arrived in the Volga German colony of Schwed on 1 July 1767. They are recorded there on the 1767 census in Household No. 29 along with a note that they relocated in 1768 to the colony of Messer.
Jakob Pfeifer, however, is recorded on the 1798 census of Schwed in Household No. Sw25.
The 1767 census records that Anna Margaretha Pfeifer came from the German village of Lauterbach.
