Peter Pfannenstiel, a craftsman (Handwerker), and his family settled in the Volga German colony of Mariental on 16 June 1766. They are recorded there on the 1767 census in Household No. 7 along with two orphaned Hertz daughters. A relationship between the Pfannenstiel and Hertz families is not recorded on the 1767 census.
In 1790, Adam Pfannenstiel moved from Mariental to Ober-Monjou.
Sophia Margaretha Pfannenstiel and her son have resided temporarily in several colonies since 1784 when her husband, Johann Pfannenstiel, was captured from Mariental by the Kirghiz. The 1798 census records that she and her children are in the colony of Beideck (Bd91).
The 1767 census records that Peter Pfannenstiel came from the German village of Manderscheid in the Kurtrier region.
