According to the Wolferborn parish records, Johann Michael Kaiser, son of Johann Kaiser of Michelau, and Elisabetha Schneider, daughter of Johann Melchior Schneider of Michelau, were married on 12 Mar 1711. Among their children was Johann Thomas, who was baptized on 19 Aug 1725. There is no marriage record for Thomas in the Wolfersborn parish records, so he must have departed for Russia as a single man. He is recorded in the Norka First Settler's List (Family #108) with his wife Christina and her sister.
