The F. G. Williams House is a historic house in Somerville, Massachusetts. The 20-room, 2.5-story wood-frame house was built c. 1855 for Frank G. Williams, a dealer in kitchen furnishings, and is one of the city's best examples of a center-gable Italianate house. Details include the trefoil window in the center gable, round-arch windows in the side gable ends, as well as carved brackets under the deep gables and an ornate porch and window enframement.[2] Purchased in 1955 by John and Genevieve Daly, they completely restored the exterior, including new roof and gutters in 2015.
