Waterford is an unincorporated village and census-designated place (CDP) in the Catoctin Valley of Loudoun County, Virginia, located along Catoctin Creek. Waterford is northwest of Washington, D.C., and northwest of Leesburg. The entire village and surrounding countryside is a National Historic Landmark District, noted for its well-preserved 18th and 19th-century character. In the 1810 United States Census, the population center of the United States was recorded as being just northwest of the village. History Founding Waterford was established around 1733 by Amos Janney, a Quaker from Bucks County, Pennsylvania. Janney purchased on the south fork of Catoctin Creek and established a grist mill and saw mill in the area in the 1740s. Due to the success of the mills, the settlement became known as "Janney's Mill." The town grew quickly as a center of commerce for growers of grain. Growth Amos Janney died in 1747, leaving his estate to his sixteen-year-old son, Mahlon, who replaced the original log mill with a two-story structure. The village continued to grow, and in 1780, on the south side of Main Street were subdivided into 15 lots, upon which shops and homes were built. By the 1790s, the village was known as "Waterford", named after the city of Waterford in Ireland, where some of its founders had once lived before immigrating to the United States. New residents continued to come from Pennsylvania, as Quakers were followed by Presbyterians, Lutherans, Baptists, and Methodists. Waterford was also populated by African-Americans, both free and enslaved. Civil War By the start of the Civil War, the population of Waterford remained largely Quaker. As pacifists and abolitionists, the Quakers remained loyal to the Union throughout the war. Waterford was the scene of a fierce fight between the county's Unionist and Confederate partisan units, the Loudoun Rangers and White's Rebels, respectively. In those days, it was the home for mostly Quakers who helped slaves escape to the North. Waterford today With the town falling into disrepair in the early part of the 20th century, the Waterford Foundation was formed to help save and preserve Waterford and its history. In 1974, the Waterford Foundation helped create an innovative land preservation program in which the historic properties of Waterford are protected through open space and façade easements. More than 60 easements have been granted. The town today is largely residential, although a number of businesses are based in the village. The Loudoun
