Lawrence Washington (1718-1752) was George Washington's brother and mentor. He married Anne Fairfax (1728-1761), daughter of Colonel William Fairfax of Belvoir, himself a land agent for his cousin, Thomas Fairfax, 6th Lord Fairfax of Cameron. George accompanied his brother Lawrence to the warm springs at Bath (present-day Berkeley Springs, West Virginia), which Lawrence visited frequently to cure his ailments. On Lawrence's death, George inherited his estate at Mount Vernon, which Lawrence had named in honour British admiral Edward Vernon, with whom Lawrence had served. He died because of a major illness.
