came of age, an event which would not occur until 1809, although it also allowed his widow to occupy the property for the rest of her life. In fact, a month after her husband's death, Elizabeth Barnes Mason gave birth to his posthumous third son, Richard Barnes Mason, who would become a career U.S. Army officer and temporary governor of the California territory before his death in 1850. George Mason V's eldest daughter Elizabeth Mary Ann Barnes Mason (9 March 1785–25 March 1827) married her distant relative Alexander Seymour Hooe, son of Seymour Hooe and Sarah Alexander, at Lexington on 22 April 1802. The following year, the widowed mother remarried, to George Graham, who had been educated alongside George Mason's two youngest sons before attending Columbia University in New York and returning to become a Virginia lawyer as well as operate his family's properties after his father died in 1796.

When that George Mason (who never had children) died of typhoid fever in Portland, Oregon in 1888, the property, which was becoming overgrown, was inherited by his sister Kora Chase, who sold it in 1903 to James D. Yeomans, a local real estate speculator as well as
