Southwest Ohio Northern Kentucky Association
The northern part of the association contains the greatest concentration of Christian-heritage congregations in the Ohio Conference, many having been founded by settlers from North Carolina and Kentucky in the 1810s and 1820s. Some of the Cincinnati-area congregations were started originally as Evangelical Protestant churches, a German-language free-church movement that first appeared in the Pittsburgh, Pa. area in the early 19th century. In 1925, this small group joined the Congregational Christian Churches; some of its churches were also located in Indiana and St. Louis in addition to Pittsburgh and Cincinnati. Congregations deriving from this heritage will be marked.

Western Reserve Association
Many, if not most, churches in this five-county association carry on much of that politically and socially progressive mission and advocacy to this day. Moreover, the E&R-heritage congregations in the region were generally less inclined toward traditionalism than those elsewhere in Ohio, adding their ethnic flavor to a quintessential "Yankee" church. The association's territory encompasses virtually all of the Cleveland metropolitan area.
Because Cleveland houses the national headquarters of the UCC, many of the ordained staff members there hold their ministerial standing in this association.
