hello--my gg grandparents were Karl Joseph and Magdalena (Kreig) Zueger, from Schwyz, Switzerland. They emigrated to San Francisco in the mid 1890s, lived in the city a few years and then moved north to Sacramento. They had two daughters whose married names were Elise A. Durrer (1872-1966) and Albertina Marty (1874-1955). The daughters lived out their lives in Sacramento, CA.
Karl's name was variously spelled as Carl and as Charles.
