Andrew BLACK, b. abt 1836 (m. Susanna); had children: Sarah Elizabeth, b. abt 1859; George, b. abt 1861 (m. Vinnie); A. Lincoln b. abt 1866; and Anna Mary, b. abt 1869. Who are Andrew's parents? I've been told the name changed somewhere from SWARTZ to BLACK. One of his ancestors is possibly Michael SWARTZ who purchased a Ferry Line in Bucks County in 1769. Any help would be greatly appreciated. Danel
