Conrad Wilhelm Hergert, son of Kaspar Herget (1705-1766) & Barbara Maria Schleuning (1715-1747), was born in Nieder-Seemen in 1742.
Conrad, along with his wife and newborn daughter, arrived in Yagodnaya Polyana on 16 September 1767 and are recorded there on the 1767 Census in Household No. 32. Also living in the household are his siblings: Anna Kunigunde (age 14) and Johann (age 8).
In 1783, Johann & Kaspar Hergert moved from Yagodnaya Polyana to Frank, and then to Dönhof.
