From the Clyde Enterprise, Clyde, Ohio, January 23, 1908: Henry T. Barnum died at his home on Amanda Street last Sunday morning at 9 o'clock, aged 77 years, 3 months and 7 days. The funeral was held on Tuesday. The remains were brought to McPherson Cemetery where the interment took place. Mr. Barnum's life was in many ways a notable one. Born in Danbury, Connecticut in 1830, he was left an orphan when two years old. When hardly out of his teens, he came to Ohio making the journey by stage, settling first at Norwalk, where he learned the watchmaker's trade. In 1851, he joined the gold seeker's army and went to California and spent 16 years in the mining camps of that state. In the meantime he made several trips back to Ohio, one round trip being made by way of the Isthmus of Panama and over the route of the famous canal; another by way of Nicaragua, and one over and by the primitive methods of travel in use in the early days. He finally located in Clyde in 1867, and this has since been his home. He was engaged in business of various kinds until about 6 years ago when failing health compelled him to abandon physical labor, and since that time he has been a great sufferer and has been seen but little among our people though all held a kindly interest in his welfare. Mr. Barnum leaves two children, W. H. Barnum of Fremont and Clarence Barnum of Reno, Nevada. Their mother who before her marriage was Charlotte Stevenson of Townsend Township died many years ago. He also leaves a widow, Mrs. Julia Reynolds Barnum who with her son, A. J. Reynolds now of Cleveland did everything possible to ease his declining days.
