Looking for Mandl Family Members from Weilach Bavaria

Several members of the Georg Mandl and Nothburg Lenz family immigrated from Weilach in the late 1880s to America.
Two brothers, Andreas and Joseph, and two sisters, Theresia (Sheupp) and Maria (Arzberger) immigrated to the USA. Two sisters remained in Germany. One was married to a Gammel and the other to a Schmidhuber.
