Ray was married to Charlotte Johnson (sometimes known as "Lottie") in October 1908. They had four children: Charlotte (born 1912), Hugh Jr. (born 1913), Edith Virginia (born 1918), and Mary Jane (born 1921). In March 1966, Ray was posthumously elected to the
Pro Football Hall of Fame as part of its fourth class of inductees. At the induction ceremony in September 1966, Ray's son, Hugh L. Ray Jr., accepted the honor on his father's behalf. Ray and
Art McNally, who served as head of officiating from 1968 to 1991, and was enshrined in 2022, are the only Hall inductees to be enshrined for work related to officiating. In 2014, Ray's grandson, James W. Stangeland, published a biography of Ray and American football history titled, "Hugh L. Ray, The NFL's Mr. Einstein: Master Designer Of The Modern Game." Stangeland wrote the book "to set the record straight about Hugh L. Ray's true role in American football history." ==References==
