Mary Vining (1756–1821) was a prominent American socialite from Delaware during the late 18th and early 19th centuries. Recognized for her intellect and social standing, she was a significant figure in the political and social circles of the Revolutionary and early Federal periods in the United States.
Born in Dover, Delaware, to a wealthy and politically influential family, she was the daughter of John Vining, Chief Justice of Delaware and Speaker of the Delaware Assembly, and Mary Wynkoop. Her brother, John Middleton Vining, served as a United States Senator and Representative for Delaware. Mary Vining was noted for her extensive education and her ability to correspond in multiple languages, which contributed to her reputation both domestically and internationally.
Vining is frequently cited in historical accounts for her connections to notable figures of the era. She reportedly maintained correspondences with several high-ranking individuals, including the Marquis de Lafayette and Thomas Jefferson. Her social influence was such that she was known in the French court of the late 18th century.
In historical narratives, Vining is often associated with General Anthony Wayne. The two were reportedly engaged to be married in the mid-1790s; however, Wayne died in December 1796 before the marriage could occur. Following the deaths of her brother and General Wayne, as well as the subsequent decline of her family’s wealth, Vining retired from public life. She spent her later years in Wilmington, Delaware, where she lived in relative seclusion until her death in 1821. She is buried in Old Swedes Churchyard in Wilmington.
