There are two Kohlmeier families that settled in the Volga German colony of Graf on 10 June 1766. The 1767 census does not record their relationship to each other.
(1) Jakob Kohlmeier, a farmer, is recorded on the 1767 census of Graf in Household No. 21 along with his wife Maria Christina, son Friedrich (age 1), and brother Mathias (age 13). In 1796, Friedrich Kohlmeier moved from Graf to Biberstein.
(2) Peter Kohlmeier's widow is recorded on the 1767 census of Graf in Household No. 32 remarried to Johann Wilhelm Stollmann. The 1767 census records that Jakob Kohlmeier came from the German village of Heilbronn in the Kurmainz region.
