Union County is a county located in the US state of Ohio. As of the 2010 census, the population was 52,300. Its county seat is Marysville. Its name is reflective of its origins, it being the union of portions of Franklin, Delaware, Madison, and Logan counties.

Union County is part of the Columbus, OH Metropolitan Statistical Area.


Early history

Union County has been under the rule of three countries in its history: France, England, and the present-day United States. It was discovered by the French explorer La Salle, along with traders and missionaries who accompanied him. After the French and Indian War, the Treaty of Paris of 1763 placed the area under British rule. Following the American Revolution, in 1783, the area would eventually become known as the Northwest Territory and part of the United States.

After the American Revolution, former soldiers from New England poured into Ohio after being granted land by the government. They surveyed the land, and sought to develop a state between Lake Erie and the Ohio River. Their proposals for the governance of the territory led to the passage of the Ordinance of 1787, which guided the establishment of states within the Northwestern Territory. Bitter struggles with American Indians over the next decades would follow, culminating with the battle of Tippecanoe in 1811, which saw the final defeat of the American Indian tribes in Ohio led by Tecumseh. A notable victim of the warring between the settlers and Indians was Jonathan Alder, who resided in and around the Union County area throughout his life.

Original settlements

The first town laid out in the county was North Liberty, established by Lucas Sullivant in 1797, but the first settlement in the county was made in present-day Jerome township by Joshua and James Ewing in 1798. An important settlement made in the county would be by Abraham Amrine, of Swiss descent and a revolutionary soldier, in 1817, two miles (3 km) northwest of Marysville.


As part of negotiations with Virginia, who had claimed land in Ohio, to sign the Articles of Confederation, the United States granted them claims to land in Ohio which would be known as the Virginia Military District. Union County would be in this district. In 1803 Ohio would become a state.

After lobbying by Col. James Curry, who represented the area in legislature at the time and a resident of what would become Jerome township, Union County was established by the Ohio legislature, and became official in 1820 with the appointment of the original commissioners: Stephen Bell, Reuben Wallace, and John Huston. The county commissioners eventually established the townships, including Union (1820), Darby (1820), Mill Creek (1820), Jerome (1821), Paris (1821), Liberty (1822), Leesburg (1825), Allen (1827), Jackson (1829), York (1834), Washington (1836), Dover (1839), Claibourne (1834), and Taylor (1849), while they designated Marysville as the county seat.

The town of Milford was established in 1816 by George Reed, Marysville in 1819 by Samuel Culbertson, Richwood in 1832 by Philip Plumber, Kingsville in 1834, Somerville in 1835, Watkins and Arbelia in 1838, Newton in 1838 by David Paul, York Center in 1841, Frankfort in 1846, Unionville in 1847, Pharisburg in 1847, New California in 1853, Dover in 1854, Union Center in 1863, Broadway in 1865, Pottersburg in 1869, Peoria in 1870, Magnetic Springs in 1879, and Claibourne in 1881.

After the organization of the county by the Ohio Legislature, Marysville was designated as the seat of Union County. The first recorded meeting of the commissioners was in 1820. Between 1835 and 1840, a courthouse was constructed. Eventually a new courthouse would be built in Marysville, dedicated on January 27, 1883. This is the present courthouse today.

In 1849, a county infirmary was authorized. The first county jail was a log structure that sat on the southside of East Center street, in the rear of the courthouse. Eventually a new jail was authorized by the commissioners and built in the 1870s. In 1878 the county purchased a 10-ton safe for the treasury, that eventually was moved into courthouse.

The first county fair was held in 1847 in Marysville, in the public square. In 1852, the Agriculture Society moved the fair to the current location, on the northside of town. The Bible Society was organized in 1830. On December 4, 1875, a group met at the courthouse in Marysville to organize the Union County Pioneer society. The original members were: Eliphas Burnham, George Snodgrass, John F. Sabine, William Porter, Tobias Beightler, Abraham Amrine, Samuel Reed, Ray G. Morse, Josiah Westlake, Josiah Reed, William. M. Robinson, Hiram Kent, Edward Powers, George Reed, Robert Graham, Samuel Gamble, A. A. Woodworth, George Mitchell, Taber Randall, Joseph Dodds, William Phillips, Thomas Snodgrass, Robert Snodgrass, A. P. Robinson, R. L. Partridge, and Hylas Sabine.

In 1866, the Union County Teachers' Institute was organized in Marysville, with Franklin Wood serving at the first President. In 1882, the Normal School was organized by J.S. Wharton, which specialized in instructing future teachers.

Early growth


The county lacked transportation infrastructure until 1812 when the first known highway named Post Road was constructed across the southern portion of the county. In 1844 the legislature by act created a free turnpike that ran from Columbus to Bellefontaine, passing through Marysville, originally costing $230,000. This road eventually became what is known as U.S. Route 33 today. In 1853, the Marysville and Essex Plank Road Company was organized and constructed a road from Marysville north, through Pharisburg. The company sold capital stock for $30,000, and this road today is known as State Rt. 4. By 1915 the county had built 705 miles (1,135 km) of roadways, the most of any county in the state for its size.


By the late 19th century and into the 20th century, the county began developing its electricity infrastructure. By 1915, electricity lines ran from Magnetic Springs to Richwood.

The county's first railroad was constructed between 1850–1854, a line that ran from Springfield to Delaware and crossed through the county in Milford, Marysville, Irwin, and Dover. A railroad called the New York, Pennsylvania, and Ohio line was chartered in 1851 and would eventually run through Union County with station points at Richwood, Woodland, Claibourne, Pottersburg, Broadway, and Peoria. The Columbus and Bellefontaine railroad was incorporated in 1878 and had station points in the county at Marysville. The Toledo and Central railroad ran from Columbus north through the county, with station points at Marysville, Peoria, and Raymond.

The first telegraph line was completed in 1859, which connected Marysville with the world via Springfield.

Because of the fertile soil in Union County, the county's farmers required minimal fertilizer. There were hundreds of farms in the county in its early stages. The crops grown in Union County's early history included wheat, oats, corn, Irish potatoes, clover and alfalfa. The county was a large producer of milk, butter, sugar, syrup, apples, and pears.

In 1911, 270,000 acres (1,100 km2) were owned in Union County, with 85,000 cultivated for farming. The farms had a total of 9,355 horses, 8,110 milk cows with 14,000 total cattle, 43,727 sheep, and 32,000 hogs. 312,000 pounds of wool was produced that year.

Union County was home to many industries in its original days from hotels, tanneries, distilleries, breweries, mills, asheries, manufacturers, energy production, banks, grocers, and retailers, among others. Marysville's industrial roots can be traced back to many early companies. Among those were the Marysville Pearlash Factory, an ashery founded in 1848, which by 1874 was the largest in the United States. The first steam-grist mill was erected in 1856 by Saxton and Casil.

Magnetic Springs, following the discovery of natural healing waters, became a tourist haven in the late 19th century until the innovation of modern medicine in the early 20th century. Tourists from all over the world visited the springs and stayed at resorts such as "The Park" and "The Columbus". "The Park" was home to the "Sager Sanitarium Bath".


Union County had many medical professionals from its earliest days. They included Dr. David Henderson, a civil war surgeon and descendant of the House of Stuart, Dr. T.B. Asbury, educated at Berkshire Medical College in Massachusetts and the nephew of Francis Asbury, Dr. J.S.

Union County was home to many notable jurists in its early history, including John F. Kinney, who practiced in Union County in 1836 and eventually became a supreme court justice in Iowa and later a congressman from Utah. Edward Stillings grew up near Milford Center and was a graduate of Harvard, and became one of the top jurists in the country, practicing before the United States Supreme Court and helping to form the legal code of Kansas in the 1870s. James Wallace Robinson was a native of Union County and went on to become a U.S. congressman in 1872. James E.

Publishing exerted great influence over public opinion in the county in its early days. Monthly and weekly publishings were the earliest known forms of the media in the county originally. The earliest known newspaper in the county was the "Our Freedom and Union County Advertiser," first published in Marysville in 1839 by Stephen McClain, Robert McBrattney, and William Lawrence. The newspaper was then renamed the "Union Star" after a year and continued until May 1841, when it was purchased by John Cassil and renamed the "Union Gazette". In 1842 the paper moved to Bellefontaine and was edited by Thomas Robb, with the paper sent weekly to Marysville. In 1843 the paper moved back to Marysville and was published until 1844. During the period it was owned by Cassil, it politically leaned Democratic.

In 1844 the paper was purchased by P.B. Cole and W.C. Lawrence, who renamed it the "Argus and Union County Advertiser" and moved the politics toward the Whig party. In 1845 the paper was sold to James Alexander, and after only six weeks, sold back to John Cassil, who turned the paper back into a Democrat political newspaper. In 1846, P.B. Cole bought the newspaper back and turned it back into a Whig political newspaper. In 1849, he sold the paper to C.S. Hamilton, who renamed it the "Marysville Tribune". A notable printer of the Marysville Tribune was Preston Plumb, who eventually left Marysville and became a U.S. Senator in Kansas. The paper would eventually be purchased by the Shearer family, who published daily editions that were Republican-leaning, and weekly editions that were independent.

Other papers in the county were the "Eaglet", formed in 1845, and lasting only a few months. The "Union Journal", formed in 1853, lasted a year. It would be moved to Xenia, where it became the Xenia News, and edited by Whitelaw Reid. The "Union Press" was formed in 1858 by Hylas Sabine and Republican-leaning. In 1863 it was purchased by the Vallandighamer family and changed to the "Union Democrat", which changed the paper in politics and spent its time attacking the Union government during the American Civil War. It ceased operations in 1864. In 1883 the "Darby News" was formed in Milford Center and eventually became the "Milford Echo" before folding, the "Milford Ohioan" was formed in 1887, the "Richwood Gazette" in 1872, the "Richwood Reporter" in 1882, which ceased operations two years later when destroyed by fire, and the "Octograph Review".

In 1874, the "Marysville Journal" was formed by C.M. Kenton, later becoming the "Union County Journal" and leaned Democratic. By 1883, the "Marysville Tribune" and the "Union County Journal" were the only newspapers published in the county. Eventually the two papers would merge and become what is known today as the Marysville Journal-Tribune.


The pioneers who composed the large majority of county residents in the early 19th century were generally very poor, meaning that there was no need for a bank in the county's early years. Trade was done by barter, including the exchange of coon and deer skins, whiskey, honey, and other durable goods. The state bank issued currency in the early periods known as "red dogs," "wildcats," and other currencies which passed through the county, with the book the "Bank Detector" published weekly to inform consumers of exchange rates of these currencies. Gold and silver was of little value in the early days, and what banks were formed usually failed.

After some banking laws were passed and the production of the county grew, currency gained value in trade, including paper, gold, and silver, and banks were permanently established in the county. The first bank in the county was the Bank of Marysville, established by Andrews, Evans, and Woods in 1854, with its first advertisement appearing in the Marysville Tribune. By 1863 they were selling the U.S. government "520 bonds". The Farmers Bank of Union County was established in 1868 on the Robinson block just east of the public square in Marysville, and by 1904 had merged with the Union Banking Company of Marysville. The Citizens Home and Savings Company was incorporated in 1889 with a million dollars in capital, located in the Liggett Building in Marysville. The Peoples Bank was organized in 1874 in Marysville, with its President being A.J. Whitney. In 1890 the Union Banking Company of Marysville was organized in Marysville by Snider, Asman, David, and Sellers. In 1909 the Commercial Savings Bank was established in Marysville by Braun, Blue, Southard, and Thorp.

In 1904 the Deposit Bank was established in Raymond. Banks were formed in Milford Center including the Milford Center Bank in 1878 by Fullington and Phelps, and the Farmers and Merchant Bank of Milford Center in 1907 by Erb, Reynolds, and Burson. The first bank in Richwood was formed in 1866 by Davis and Allen, but quickly failed. In 1867 the Bank of Richwood was organized by C.S. Hamilton, and would eventually become what is known today as the Richwood Banking Company. The Union County Bank was formed in 1874 in Richwood by Cratty and Blake, the Farmers Deposit Bank of Richwood in 1884 by W.H. Conkright, and the First National Bank of Richwood was formed in 1908 by L.J. McCoy.

Military heritage

Union County has a military heritage dating back to the American Revolution, and was a frequent location for the organization of military companies. Because the government paid the soldiers with land grants in the west during the revolution, Union County became home to many of these soldiers after the war. A notable soldier was Col. W.L. Curry, who served on the Virginia Line. A recorded 14 soldiers from the revolution eventually made their way to Union County, with many others unrecorded because of poor record keeping.

The War of 1812 broke out with early battles fought in the Northwest Territory, including Lake Erie. A descendant of a hero, Oliver Hazard Perry, from the War of 1812, named Robert S. Beightler, was a native of Union County. A company of 13 Union County men was assembled for this war, with many other natives of Union County joining companies from outside the county, including a company formed by Jonathan Alder. Over 100 natives of the county would serve in the war.

When the Mexican War broke in 1845 following the annexation of Texas into the United States, Union County enthusiastically provided men, totalling over 30.

The American Civil War followed, which was not greeted in the same manner the previous war was. However, Union County would provide 3200 men for that war, suffering the casualties of 1,035 wounded, killed, or missing, while producing notable leaders such as Norton P. Chipman. They fought in 31 principal battles, from Bull Run to Appomattox.

Union County would produce veterans from the Spanish–American War, World War One, Mexican Conflict, World War Two,Korean War, Vietnam War, Persian Gulf War, the Iraq and Afghanistan Wars, and the War on Terror, as well as other conflicts throughout the United States' history. Marysville native Cornelia Cole Fairbanks, wife of U.S. Vice President Charles W. Fairbanks, would serve as President of the Daughters of the American Revolution in the early 20th century.

In 2007, the Union County Veterans Remembrance Committee dedicated the Union County Veterans Memorial on the northeast lawn of the courthouse. This was sponsored through private, public, and corporate grants and donations, including support from the Union County Foundation. In attendance were hundreds of citizens, U.S. Representative Deborah Pryce, and many other political and civic leaders. In 2008, the Ohio National Guard opened a new $8.2 million Marysville facility on the eastside adjacent to the YMCA. The Ohio Army National Guard headquarters in Columbus is named after Marysville native Gen. Robert S. Beightler.


According to the U.S. Census Bureau, the county has a total area of 437 square miles (1,130 km2), of which 432 square miles (1,120 km2) is land and 5.1 square miles (13 km2) (1.2%) is water.
