Looking for info concerning the family of Charles (1822 Pru) and Augusta (1828 Pru) ZAHL. They appear on the 1870 census of Waupaca Waupaca WI, with Mary 1851 PRU, Charlotte 1855 OH, William 1857 OH, Anna 1859 OH, Lydia 1865 WI, and Phillip 1869 WI. In 1880 Charlotte, Wm, and Anna appear with their sister Mary (Henry) BRINKMANN on Milwaukee Miwaukee WI census. I can not find them on 1860 census in OH. Also, what happened to missing family members between 1870 and 1880? What happened to Mary's three siblings after 1880. Any help would be most welcome. Thanks, Chuck
