The names fit, but the dates are iffy. My grandmother Lizzie Ketchen was born 1856 was the oldest child of John Ketchen and Janet? Mathewson. Janet? died in about 1861. Lizzie was about 5 at the time of her mother's death and had two younger brothers age 5 & 2. John married a second time to a Mary Patterson. I hope this connects.I would appreciate any Ketchen info and pictures you have. Email me directly if you wish. Thanks
