The Milners represent an outstanding example of Alberta’s service to Canada’s military. Seven family members, including fathers, brothers and wives, served from the First World War to Stanley Milner’s work with the South Alberta Light Horse Regiment. Stanley Milner exemplified his family’s commitment to the military, serving in the 2nd Battalion, Saskatoon Light Infantry and the Canadian Officer Training Program. He also served as Honourary Colonel of the South Alberta Light Horse Regiment and founded the South Alberta Light Horse Regiment Foundation, a group which preserves regimental history and provides support for retired soldiers and military families. He was also a successful businessman, city alderman and philanthropist

In 1996, the library was officially renamed the Stanley A. Milner Library in his honour.
