Eunice Dennie Burr

Eunice Dennie Burr (1729—14 August 1805) was an American socialite in Connecticut. She and her husband Thaddeus Burr were considered the "first couple" of Fairfield, Connecticut in pre-revolutionary times. 

Eunice Dennie Burr was born in 1729 to James Dennie (1702–1784) and Eunice Dennie (1708–1740). She married Thaddeus Burr in 1759. Before the American Revolution, their house hosted John Adams, Samuel Adams, Aaron Burr, John Hancock, and George Washington. 

In 1779, their house was burned by British soldiers under General William Tryon's command; the soldiers also looted the house and stole Eunice's rings, buckles, and silver buttons, and Eunice hid from them in the marshes behind her house. The house was rebuilt by Eunice and Thaddeus in 1791. For its rebuilding, John Hancock presented the frame, as his own house frame was the model after which the Burr mansion (as it is now known) was built, though the Burr mansion has changed since.

In 1804, Eunice bought nine shares of the Fairfield Academy for $5 on the condition that young women would be allowed to attend classes there.

The Eunice Dennie Burr Chapter of the National Society Daughters of the American Revolution is located in Fairfield, Connecticut.

Eunice died on August 14, 1805, in Fairfield, Connecticut, at the age of 76.
