Three tombstones in Green's Prairie Cemetery are for an Ellis family. John (died Feb 2, 1864 at age 42y, 3m, 19d), Edward J. (died June 25, 1864, age 15d, son of J. & C), and George M.(died Oct. 17, 1864, age 6y, 5m, 5d, son of J.&C.). Have not found found the family in the census, Ancestry trees, land records. Only clues are an article about the sudden death of a John Ellis in the 1844 History of Green County and a Civil War draft registeration card for a John Ellis in York Township. Anyone know this family?
