The Atlas of Warren Co., Indiana [1978] says this about Medina Township

[1877] MEDINA TOWNSHIP

Located in 1827, is the northeast township in Warren County. Settlement began in this township as early as 1825. During this year, James Bedle, John Stanley, Samuel Stanley and John Reed settled in the township. In 1826, John Anderson, Jeremiah Davis and his son George Davis became citizens of the township. Edward Moore and Thomas Moore his son, Horatio Baily, William Baily, Thomas Johnson and sons - George, James and Daniel - Thomas Boyer and Jeremiah Foster moved into the township. In 1829, Edward Mace, Thomas Dawson and Aaron Stevenson became settlers, while Josiah McGee came the next year, or 1830.

Several of these men still live in the Township, honored and respected citizens, while others have moved away or died.

The southeastern part of Medina township is hilly and cut with ravines and gorges. The north and northwestern portion is gently rolling prairie. The northeastern part, near the line of Benton County, is level and marshy, and is known as "Pond Grove." Careful drainage has rendered this land productive, however, save in excessively wet seasons.

Although the surface of this township is varied, yet in the greater portion abound choice farming lands, which were settled and improved in an early day. The enterprise and thrift of the citizens is apparent in buildings, fences and fine stock. The former home of Gen. Wagner, a gallant soldier in the late conflict for the Union, is situate in the northwestern portion of the township.

The soil in the southeastern portion of the township is a clay loam. In the northern and western portions is a rich black sand-loam - very productive. Little Pine Creek, with its tributaries, furnishes very good drainage and stock water. At a convenient distance beneath the surface, plenty of living water is found. The town of Green Hill is situated on the left bank of Little Pine Creek.

This town, formerly known as Milford, was platted in 1835. It has a population of 100. The Upper Wabash Conference of the United Brethren Church erected a very fine building in the grove south of and adjacent to the village, for Conference School purposes. The institution bears the charter name of "Green Hill Seminary." A competent corps of instructors is employed by the Board, and the facilities for acquiring a thorough education are second to none in the State.

There are more resident ministers at Green Hill than in any other town in the county.

There are two dry goods stores, one grocery and drug store,, two practicing physicians, one blacksmith shop, one church, one district schoolhouse and the Seminary building, in Green Hill. Rev. George Davis, Horatio Baily and Aaron Stevenson, pioneers of the county, reside at this place.
