1880 South Macon, Macon Co, IL. The census that year recorded John at 34, a farmer, Martha was 29. Children included Eda, 8; Minnie, 6; and Cora, 3. John also told the census taker his mother was born in PA.
6/1/1900 Same place. Again listed as John in the census, he was 54, married 30 years to Martha, 49, who had birthed 4 children, all living. Children in the house were Cora, 23, and Frances, 7. John was a landlord, as were his father and brothers.
Unless he was born prematurely, his birth date conflicts with next older brother, David, who is only 8 months older.
There may be a death date discrepancy as he was not listed as a
survivor of his father in 1909.
