But even as his college rose, his life took a downward trend. He turned 60 in 1756. That year he lost his first grandson. That same year his beloved son William "Billy" died of smallpox on his ordination trip to England. His wife Charity died of smallpox in 1758. His step-daughter Anna and his student and wife's nephew Gilbert Floyd died in 1759. His stepson Benjamin Nicoll, his best tutor Daniel Treadwell, and his fellow Great Apostate Rev. Wetmore died in 1760. On June 18, 1761 he married Sarah Beach, the widow of his old friend William Beach, and his son's mother-in-law, and for a brief time he was "very happy". In 1762, Johnson and the board of Governors hired the Oxford-trained minister Myles Cooper, a young man recommended by the Archbishop of Canterbury, as professor of moral philosophy with the expectation that Cooper would someday succeed him. Johnson quickly bonded with Cooper, who "was with him as a son". However, on February 9, 1763, Johnson lost his second wife Sarah to smallpox, and a few weeks after, amidst an unpleasant controversy with the Board of Governors over funding his pension, "he committed the care of his affairs to Mr. Cooper", and returned to Stratford by sleigh during a snowstorm.
