At one time Mary lived with a John Sachs at Chilicothe, OH.
On 9/24/1850 Mary lived with daughter Susan and Charles Presler in Mitchie, Fountain Twp, Monroe Co, IL. Mary was 61.
This may or may not be Mary Van Gundy Carpenter. If they moved to IL, it is unlikely that she moved back to OH after Sebastian died since she had children there and her brother David was just a couple of counties away.
