Ruth Cleveland was especially beloved. When she died of diphtheria at age 12, the Curtiss Candy Company named a candy bar after her: the “Baby Ruth.”
It's highly unlikely that the Baby Ruth candy bar was named for the daughter of President Grover Cleveland. The Curtiss candy bar company did not exist until 1916, 12 years after her death. The bar was created in 1920 when Babe Ruth totally destroyed the previous home run record (his own), hitting twice s many home runs than he did in his previous record, set in 1919.
