## History

There are numerous coal exposures on the banks of the branches of Cedar Creek both north and south of Marysville. In 1846, one exposure south of Marysville was found to be on fire, and this fire continued until June 1851, when heavy rains and flooding extinguished the fire.
The county surveyor, Joseph Brobst, filed a plat for Marysville on March 4, 1851, creating 26 lots and a public square that was later subdivided into additional lots. Marysville was named after the 5 members of the Brobst family who were named Mary. Originally, the Marysville post office was named Ely or Ely's. A Methodist church was established in 1867, a weekly newspaper, the Marysville Miner, was established in 1871, and a woolen factory was opened in 1872. Marysville was officially incorporated as a town in the late 1870s, and by 1910, it had three general stores, a post office, a 4-teacher public school, and telephone service.
A five-foot bed of coal was exposed along North Cedar Creek about 2 miles north of Marysville, and by 1867, several coal banks were open in the Marysville area and Jacob Kline had opened a mine about a mile north of Marysville, where the coal was 10 feet thick. By 1908, eleven different mines had been worked in the Marysville area, primarily by the Mammoth Vein Coal Company, which took over from the O.K. Coal Company in 1903. The Wabash Railroad built a 7-mile spur line to serve the mines.
