My maternal great grandfather Caspar Rubli lived in canton Zurich in the middle 1860s. He married a lady named Marie Nohl, and they had five children. At least two of the children claimed in later life that the town of Dachsen was their home. One of the children named Barbara claimed a birth date of July 22, 1866, and named Winterthur as her last residence before emigrating to the United states. The names of the other four children were Caspar, Elsie, Marie, and Salome who emigrated to the United States with her sister Barbara in the year 1881. I would like to learn the birthplaces and birthdates of the rest of the children, the birthplaces and birthdates of their father and mother, and the place and date of their marriage. How could I go about learning this information? I do not speak or read German. Thanks for any help anyone can offer, Russell Buster
