Lord Fairfax sent for Martin, who arrived in Virginia from England aboard the "Hatley" on May 24, 1751, accompanied by William Fairfax, who had been seeking an appointment to a position in England. Martin and Fairfax arrived in Williamsburg, where they dined with Fairfax's fellow Virginia Governor's Council member John Blair, Sr., and visited the Governor's Palace and the Capitol before beginning their journey toward the Northern Neck on May 31. Following his arrival at the Northern Neck Proprietary, Martin settled at Greenway Court with his uncle that autumn. Due to his humble upbringing, Martin quickly adapted to frontier life at Greenway Court. He soon earned the affections of Lord Fairfax on account of his energetic nature, his loyalty, and his good eyesight, which greatly assisted his myopic uncle. On May 21, 1752, shortly after Martin had come of age on his twenty-first birthday, Lord Fairfax granted Greenway Court to his nephew, along with of limestone lands on the west bank of the Shenandoah River across from Leeds Manor, which were "to be known and called by the name of the Manor of Greenway Court" and subject to an annual quit-rent fee of "a good buck and doe" due on the feast day of Saint Michael the Archangel. Greenway Court had taken its name from the Culpeper family's manor in Kent.
