Hi, Bill! My father is William (Bill) H. Hartz of IL(1918-}, his father William Homer Hartz of IL(1887-1970), his father Irving Thomas Hartz of IL (1861-1929), his father Samuel B. Hartz of Peoria, IL(1837-1891) married twice to Virginia E. Thomas and Stata Buckner (3 sons by each - Virginia was Irving's mother) and served in Illinois regiment beginning 1862, his father Samuel Hartz (1800-1871) married Mary Brightbill. There are notes saying we're descended from John Hartz in PA, but cannot find the connection. Can you help? Thanks!
