Mattis (Kaneau)*
Leonhard Menges from Senck & Anna Regina Mathes, a widow, were married 28 April 1766 in the Lutheran Church of Büdingen.
Leonhard Menges (age 26), a farmer, his wife Anna, and [step?-]son Georg (age 10¼) arrived from Lübeck at the port of Oranienbaum on 31 July 1766 aboard a Russian ship under the command of Lieutenant Samuel Gibbs. Leonhard is not old enough to have a son who is age 10, so Georg is believed to be a stepson with the surname of Mattis.
Johann Georg Mattis (age 10) is recorded on the 1767 census of Kaneau in Household No. 57 along with his stepfather Georg Friedrich Baschka.
The Baschka family moved to the colony of Schaffhausen in 1786, and Johann Georg Mattis could have accompanied them there.
The 1767 census does not record a location from which Johann Georg Mattis came.
There are no known surviving male lines of this family among the Volga German colonies.
