Charles Carnan Ridgely was born Charles Ridgely Carnan. He is also known as Charles Ridgely of Hampton. He served as the 15th Governor of the state of Maryland in the United States from 1815 to 1818. He also served in the Maryland House of Delegates from 1790 to 1795, and in the Maryland State Senate from 1796 to 1800. Charles was born in Baltimore. He was the son of John Carnan and Achsah Ridgely, sister of Captain Charles Ridgely. The Maryland Gazette described him as an aristocrat.

Hampton National Historic Site, in the Hampton area north of Towson, Baltimore County, Maryland, preserves a remnant of a vast 18th-century estate, including a Georgian manor house, gardens, grounds, and the original stone slave quarters. The estate was owned by the Ridgely family for seven generations, from 1745 to 1948. The Hampton Mansion was the largest private home in America when it was completed in 1790 and today is considered to be one of the finest examples of Georgian architecture in the United States. Its furnishings, together with the estate's slave quarters and other preserved structures, provide insight into the life of late 18th-century and early 19th-century landowning aristocracy. In 1948, Hampton was the first site selected as a National Historical Site for its architectural significance by the U.S. National Park Service. The grounds were widely admired in the 19th century for their elaborate parterres or formal gardens, which have been restored to resemble their appearance during the 1820s. Several trees are more than 200 years old. In addition to the mansion and grounds, visitors may tour the overseer's house and slave quarters, one of the few plantations having its original slave quarters surviving to the present day.
