After the death of Lincoln's 11-year-old son Willie in February 1862 (an event not mentioned in Hay's diary or correspondence), "it was Hay who became, if not a surrogate son, then a young man who stirred a higher form of parental nurturing that Lincoln, despite his best intentions, did not successfully bestow on either of his surviving children". According to Hay biographer Robert Gale, "Hay came to adore Lincoln for his goodness, patience, understanding, sense of humor, humility, magnanimity, sense of justice, healthy skepticism, resilience and power, love of the common man, and mystical patriotism". Speaker of the House Galusha Grow stated, "Lincoln was very much attached to him"; writer Charles G. Halpine, who knew Hay then, later recorded that "Lincoln loved him as a son".
