Konrad Ostertag was born in 1718 in Mannheim (today in Baden-Würtemberg). He married Demuth (surname unknown), and they had at least the following seven children, each baptized in the Catholic Church in Böhl, southwest of Mannheim: (1) Johann Jakob, born 1748; (2) Johannes, baptized 7 May 1751; (3) Johann Ludwig, baptized 14 December 1752; (4) Anna Maria, baptized 1 November 1754; (5&6) twins Anna Margaretha & Johann Konrad, baptized 22 August 1757; and (7) Johannes, baptized 12 July 1760.
Konrad Ostertag, a horse doctor (Pferdedoktor), his wife Demuth, and children (Jakob, age 18; Ludwig, age 13; Anna Maria, age 12; Johann, age 10) arrived from Lübeck at the port of Oranienbaum on 21 July 1766 aboard a snow-brig named Mercurius under the command of Skipper Christian Heinrich Abelßen.
Konrad's wife died during the journey between Oranienbaum and the Volga German colonies.
The Konrad and the children arrived in Sewald on 20 August 1767. They are recorded there on the 1767 census in Household No. 35.
In 1790, Jakob Ostertag and his family moved from Sewald to Husaren. By 1798 they and brother Johannes (b. 1751) were living in Dehler and are recorded there on the 1798 census in Households No. Dl23 & Dl38.
Johannes (b. 1760) moved to Volmer and is recorded there on the 1798 census in Household No. Vm29. There are no Ostertag descendants who remained in Sewald.
The Oranienbaum passenger list records that Konrad Ostertag came from the German region of Pfalz.
