"... Rudolf Hauswirth born Oct 11 1806 in Saanen, Bern, Switzerland and died Aug 10 1872 in Brookfield, Waukesha Co., Wisconsin, USA. He married Catherine Romang Nov 06 1826 in Saanen, Bern, Switzerland. She was born Jan 18 1807 in Gesteig, Bern, Switzerland and died Apr 21 1885 in Milwaukee ..."
I know you're looking for photos, but there is another type of image that is not quite as rare: the Hauswirth family published death notices for Katharina Romang Hauswirth in one of the local German papers. And there are multiple notices in the German papers for Maria (Hauswirth) Bächler's family - John Bächler Jr., Rosine, a Johann Adolph Bächler; then John Sr.; and later on Maria.
