"Farmer by occupation and some if not all of his children left Jackson Co. Ohio in 1845 and headed west. They settled in what would soon become Wapello County IA. IA did not become a state until Dec. 28, 1846. Since John had been in the War of 1812 and a veteran, he was able to purchase land and took up farming. His tombstone in the Mars Hill Cemetery southeast of Ottumwa is broken, half gone and difficult to read. Some of John's children stayed in Wapello County, some moved to neighboring Davis County and our branch moved to IL in 1847. They settled near Hermon, Knox County IL. IGS Pioneer Certificate list has John being buried in Floris, IA."
