Johann [Kaspar] Albertin, a tailor (Schneider), and his wife Anna Maria are recorded on an appendix to the 1767 census of Boisroux in Household No. 14.
In 1774 (during the Pugachev rebellion), Kaspar Albertin ran away and never came back.
The 1767 census records that Johann Albertin came from the German village of Wiseritz in the region of Böhmen (Bohemia).
