Welcome to the Denison Society and the Denison Homestead Museum website.  The Society is charged with the preservation of this historic family home located in Mystic, CT, and with stewardship of the surrounding land—140 acres, part of the original land grant Capt. George Denison was given for service to the early Pequot militia. 

We now offer two types of memberships to the Denison Society: Denison Family Memberships for descendants of William Denison, and Friends of the Denison Society Membership for anyone not related to the Denisons but interested in helping support the upkeep and restoration of the Homestead Museum and help the Society to maintain the surrounding land in its natural state. Please visit our Memberships page for more information and applications.

Built in 1717, the Denison Homestead is the third house to be constructed on 200 acres of land granted to Capt. George Denison in 1654 and is believed to be one of very few homes left in the country that has been continuously owned by the same family.  The Homestead is now owned by the Denison Society, Inc.  It currently houses the Society’s offices and the Denison Homestead Museum which is open to the public.

In 1979, the Denison Homestead was placed on the National Register of Historic Places.
