In 1917, Henry gifted Edith the first 16 acres of land where she would eventually build Topsmead. She first built a a rustic cabin and then a larger house in 1923. She expanded the house to what it is today in 1925. Edith shared Topsmead with two of her lifelong friends, Mary and Lucy Burrall. The maintained a relaxed atmosphere at the house and entertained guests informally.
Edith inherited a substantial sum when Henry passed away. She used the money wisely, investing in real estate which increased her wealth even more. One notable purchase was when she bought a farm in 1927, which provided food for the mansion. She also served on the board of the Connecticut Forest and Park Association. She passed away in 1972. In her will, she left the estate to the people of Connecticut and requested that the estate become Topsmead State Forest.
