Silas Deane House in Wethersfield, Connecticut was the home of Silas Deane, the first diplomat for the United States. Deane built the house in 1766. The two-story Georgian house is L-shaped with gable roof and two interior chimneys. In 1959, the house was donated to The National Society of the Colonial Dames of America in Connecticut and in 1963-1965, it was restored. It is now a historic house museum and includes original furniture and portraits of Deane and his second wife. It was declared a National Historic Landmark in 1972.
