There are three Rohleder families that settled in the Volga German colony of Rohleder on 14 June 1766. The 1767 census records that each of them came from the German region of Bamberg, but their relationship to each other (if any) is not recorded.
(1) Georg Rohleder (age 58), a farmer, and his wife Barbara are recorded on the 1767 Rohleder census in Household No. 1 along with a note identifying Georg Rohleder as the colony's mayor (Vorsteher). It is probably after him that the colony was named.
(2) Johann Rohleder (age 32), a farmer, and his wife Elisabeth (from the German region of Mainz) are recorded on the 1767 Rohleder census in Household No. 5.
(3) Johann Konrad Rohleder (age not recorded), a single farmer, is recorded on the 1767 Rohleder census in Household No. 43.
In 1832, Konrad Rohleder, brother of Peter Rohleder, relocated to the colony of Graf where he is erroneously recorded as Konrad Schamne in Household No. 4.
In 1834, Peter Rohleder, son of Peter Rohleder, relocated to the colony of Herzog.
