I'm also descended from Eunice Manners and James S. Manners. (=James Samuel Manners + Mary Lucy Snyder=Frederick Gilkeson Manners+Sarah Finetta Noble=Elmer Noble Manners+Dorothy Carol Hartman=Emma Louise Manners+Lawrence Herfel Coefer=Dane Lawrence Coefer (me)). You might check NJ census records to see if Dr. John Manners had any children. James S. might also have been the son of his brother Gen. James Stout Manners + Lucy Snyder. I reside in Oregon and don't have access to primary records.
