I am looking for the dates of emigration of my g-g-grandmother and her children (in about 1860-1870). Her name was Katherine Walser-Jenny. Her children were John Jacob Jenny (or Jacob John), Francis X Jenny, Alois Jenny and Louisa Jenny. (Her husband's name was John or Jacob, but I don't think he came to America). I believe they were were originally from Rankweil, Vorarlberg Austria.
