Johann Peter Balthasar and single woman Maria Elisabeth Ackermann of Kavelocherhof were his baptismal sponsors. Peter Ackermann of Kavelocherhof was his confirmation sponsor in 1781 in Klotten.
Johann Peter was a baptismal sponsor in 1784 for Anna Margarete Ackermann, his uncle Anton Ackermann’s daughter, and in 1788 for Maria Margaretha, daughter of Peter Lauxen and Veronica Berends of Wirfus. At that time he was described as being single. It is possible that this Johann Peter Claas was the person who married Maria Margaretha’s first cousin, Elisabeth Lauxen, who was born in 1770 in Wirfus. Johann Peter was a witness at the wedding of his brother Jakob and Maria Katharine Ackermann in 1807.
