Opal Trout was born in Newport, Nebraska but was raised in Kansas City, Missouri. She married Oscar S. Hill, an attorney. As she was suffering from a lingering kidney infection, her doctor recommended mild exercise and she took up golf at the age of 31. She won numerous amateur tournaments. Hill became a golf professional in 1938, and was one of the 13 founders of the Ladies Professional Golf Association in 1950. Hill died in Kansas City, Missouri at the age of 89.
