Frances Mallory's son, Richard Millikan, became a respected climber in his own right during the 1960s and '70s. Mallory's grandson, also named George Mallory, reached the summit of Everest in 1995 via the North Ridge with six other climbers as part of the American Everest Expedition of 1995. He left a picture of his grandparents at the summit citing unfinished business.
