Lorenzo Dow Barnum was named after the famous Methodist itinerant preacher Lorenzo Dow (1777–1834). As a result of his eccentricity, infamy, influence and travels throughout the country many thousands of US children of the early 19th century were named after Lorenzo Dow. The autobiography of Lorenzo Dow was at one time the second-best-selling book in the United States, exceeded only by the Bible.
He was of Uxbridge, a city northeast of Toronto, in Durham county.
