Jameson conceived the idea of annually honoring the golfer with the lowest scoring average on the LPGA Tour and, in 1952, donated a trophy for that in the name of Glenna Collett Vare.

Jameson had to stop playing golf, other than doing some occasional chipping and putting, because of pain in her wrists caused by carpal tunnel syndrome.
