• Another man prominent in the pork-packing industry was John Waddle, a native of Belfast, Ireland, who was brought by parents to western Pennsylvania about 1787, when he was four years old. Ten years later he was apprenticed to Alexander McLaughlin, of Pittsburg, a famous merchant who became afterward a resident of Chillicothe. When seventeen years old, John Waddle took a flatboat load of pork and flour to New Orleans and returned to Philadelphia by way of the Atlantic, a common route for traders. Coming to Chillicothe in 1802, he became a clerk with John Carlisle, another Irishman, born in 1771, who had come to Chillicothe with his parents in 1798. In a few years Waddle had a business of his own, was busy in pork-packing and flatboat commerce and during the war of 1812, he had important contracts for supply of the army. He lost nearly all his fortune in the troubles of 1819 and 1828, and died at Chillicothe in March, 1831.1197, p 148
