In 1836, upon the site of the Seitz Mill at Tremont, there was a small carding machine, and that year John Ross erected a small distillery, both kind of neighborhood affairs. About these had clustered several families. Ross owned land there and began to sell small lots, and shortly the whole gave a village-like appearance. Further lots were sold and soon a survey was made and a village platted. The plat was recorded in 1838. This became the village of Clarksburg. In 1836-37, the Rosses, John and William, kept a store (in the dry goods line) on the Carter corner. In 1837, a hotel, or tavern in those days, was opened by John Hupp, the Rosses retiring. Where now stands the Hotel Fennimore stood a one-story frame building almost at right angles with the street occupied by William McKinley, who boarded Elias Darnall, the schoolmaster, William Ross the Clerk, John Ballantine the Constable, then as busy as any Sheriff, and Dr. A. C. McLaughlin the physician, busy too, the place being dead ripe for a doctor. Oh! yes, we must not forget Gabriel Albin the carpenter, who constituted one of the boarders. One door east of the boarding-house, McKinley had a dry goods store, and on the opposite side was the blacksmith shop of Elias Heller. This was Tremont in 1836-37. The post office was established there in 1839, with Dr. McLaughlin as Postmaster. The name was then changed to Tremont, there being another town in the State of the name of Clarksburg. Benjamin Turman made an addition to the town in 1840. Several additions have since been made. To-day this is a flourishing little village, beautifully located in the Mad River Valley, having a population of about three hundred. It has two good church buildings that would be a credit to any city, and several fine stores; three blacksmith-shops and as many carriage shops. A steam saw-mill and a mammoth grist-mill, four stories high, in which are three sets of buhrs-two wheat and one corn-having a capacity of making ten barrels of flour per day. This mill was erected at a cost of $5,000, and is operated by Andrew Seitz. The village has also a good hotel, and the proprietor, John Fennimore, has the happy faculty of making his guests feel at home. The school of the village is held in a substantial two-story brick building, and is in District No. 3. The number of scholars in attendance, in 1880, were ninety-nine, sixty-four in the lower room, taught by Alfred Blose, and thirty-five in the upper room taught by J. E. Smiley. Prior to 1838, the Methodists worshiped at Rector Church, and in that year they erected a brick building, which, was replaced by the present fine edifice in 1880. It is a large one-story building in the shape of a letter T, with a tall spire, containing a sweet-toned bell taken from the old church. In style, of Gothic architecture. The auditorium will seat 450 people. It has a reed organ. The church is nicely frescoed, and heated throughout by hot air furnaces. The dedicatory sermon was preached April 18, 1880, by Dr. Payne, President of the Ohio Wesleyan University. The minister in charge is Rev. McHugh. The cost of the building was about $10,500. The German Reformed Church was organized in 1863, under the administration of Rev. Jesse Richards. The present building was erected in 1865, at a cost of about $4,000. While the new church was building, the congregation returned to worship in the old log structure which they first used, and had abandoned forty years before. This is an incident seldom or never occurring in the annals of church history. It stands on a hill overlooking the village. Present membership about one hundred and twenty-five. At this church is a regularly laid out grave-yard.
