There are three Schwab families that settled in the Volga German colony of Semenovka. Two of them are believed to be related because it is recorded on the 1767 census that they both came from Eichstadt(?) in the region of Kurmainz.
(1) Matthias Schwab, a farmer, and his family settled in Semenovka on 24 July 1767. They are recorded there on the 1767 census in Household No. 28.
(2) Kaspar Schwab, a farmer, and his wife settled in Semenovka on 24 July 1767. They are recorded there on the 1767 census in Household No. 30.
