The first Engelhardt to become a Russian subject was Werner von Engelhardt, who had previously served in the army of the Polish–Lithuanian Commonwealth. He converted to the Russian State religion, accepting Orthodoxy and taking the baptismal name, Yeremey Kasparovich Engelgardt. He died before 1672. His son Sigismund (Stepan, upon Orthodox baptism) was a Muscovite noble and stolnik (personal attendant upon the Tsar) and a lieutenant in the Smolensk gentry. Other sons of Werner (Yeremey) were Georg (Yuri) and Johann (Ivan), who also served as stolniks.
