(c. 1918) Originally built for banker Will Davis, this Italianate style house was purchased by Preston Martin, an attorney and father of Broadway star, Mary Martin. Mary and son, television star Larry Hagman, spent their childhoods in this house. The home is constructed of thirteen inch cast concrete walls. The concrete “fence” is a recent addition. As a young girl, Mary hid her diary in a planter box outside her second story bedroom window.
