Konstantinovka was a daughter colony in the Volga Region of Russia, settled by Lutherans in 1859 from the Volga German parent colonies of Schilling, Jost, Merkel, Donhof, Kutter and Moor. I know that there is a film from the Latter Day Saints numbered 2379339. It lists all of the immigrants to this town and also lists all of their belongings. It is in Russian, however, and you might have to contact the Church of LDS in order to get a copy of the film, as I have had some trouble finding it. I hope that helps. Trib
