Was born in Somerset County, Pennsylvania, July 9, 1798. His father, George Thomas, emigrated with his family, to Harrison County, in the spring of 1807. In 1815 Peter Thomas, then sixteen years of age, traveled on foot, accompanied by the family watchdog, a large and faithful mastiff, along a new path leading from Cadiz to the village of Wooster, and rested one night at Stibbs' mill. The next night he reached the cabin of John Raver, near the present site of Rowsburgh. The following morning he pursued his journey by paths until he struck Beall's trail, at Jeromes' place, and thence along a blazed path partly opened, to Beam's mill, three miles below Mansfield, on the Rocky fork of Mohican. Jacob Beam, the owner of the mill, was an uncle. He remained a few weeks, and returned. In 1817, his father's family came on and erected a cabin on the present site of Mifflin, believed to have been the first shingled house in the township of Mifflin. When the tide of emigration commenced, after the close of the war, the road from Mansfield to Wooster, passed through Petersburgh, as the village was then called, and it became the principal route to Richland and other western counties for emigration. Mr. George Thomas, father of Peter, kept the first house of entertainment, which was well patronized for six or eight years. In 1823, George Thomas and family located on a farm now owned by Josiah Thomas, in Orange township. Peter Thomas purchased two hundred acres adjoining the homestead, in Montgomery township, and resided upon it until about 1860, when he removed to a new residence, one and a half miles northeast of Ashland, where he deceased, February 26,1876. He was conscious of the approaching termination of his life, and was in the act of dictating a codicil to a will, when he became faint, and expired in a few moments, from paralysis of the heart. He had been three times married, and left a large and reputable family to mourn his loss. He had been a member to the Disciple church for a number of years, and adorned his profession by an upright and exemplary life. As a citizen, he was highly respected. He was a man of uncommon resolution and firmness when he had deliberately formed an opinion. He was high-toned and exact in all his transactions with men, and inflexibly opposed to every species of prevarication in morals, business and politics. He was never an office-seeker, but was always the advocate of a pure, economical and patriotic administration of the government.* He was a careful, frugal, and shrewd businessman, and had acquired a handsome property. Few men have taken a deeper interest in the prosperity of the county, and none will be more lamented.
