George Mason was born into a prominent Chesapeake region family, with extensive land holdings in both Maryland and Virginia. Mason’s father died when young George was a child. His mother took over the responsibility of the family plantations and business interests. Eventually, George and his two siblings each inherited substantial properties.
When Ann and George married, they lived in a house on land owned by George. They soon decided to build a new, fashionable home for their growing family. They located their new home near the Potomac and called it Gunston Hall.
The Mason family at Gunston Hall took different shapes at different times. Ann and George moved into Gunston Hall with numerous children. With births, deaths, and marriages, the household evolved. It eventually included nieces and nephews, a step-mother, and aunts, as well as adult children and grandchildren. The Mansion overflowed with the nine Mason children who survived childhood, various relatives, and friends.
