I am trying to locate anyone who has done research on the Mumenthaler line from Langenthal, Canton of Bern, Switzerland. I am trying to locate information on Samuel Memuenthaler chr. September 19, 1824 in Langenthal and his wife Maria Anderegg born January 6, 1827 in Oberbipp, Bern, Switzerland. Samuel's parents were Samuel Mementhaler and Barbara Steiner. Maria Anderegg's parents were Johann Ulrich "Johannes" Anderegg and Anna Gander.
