Konrad Bischoff was born about 1719 in Zwingenberg, south of Darmstadt, the eldest son of Wilhelm Bischoff.
Konrad Bischoff, a farmer, his wife, and son Philipp (age 12) arrived from Lübeck at the port in Oraninenbaum on 12 September 1766 aboard the Love & Unity under the command of Thomas Fairfax. The Zwingenberg Mannschaftsregister does not include this 12-year-old son.
Conrad Bischoff and his wife Elisabetha are recorded on the list of colonists being transported from St. Petersburg to Saratov in 1767.
Konrad Bischoff, a farmer, and his wife Anna are recorded on an appendix to the 1767 census of Paulskaya in Household No. 5 along with orphan Heinrich Weiner (age 17). The 1767 census does not record a relationship between the Bischoff and Weiner families.
Descendants of this Bischoff family do not appear on the 1798 Census in any colony.
There are no known surviving male lines of this family among the Volga German colonies.
