Susan Gilbert Power was born in 1860 in Monaghan, Ireland. She was the daughter of William Power, who was Commissary General in Chief of British army in India and was later knighted. Following the death of his wife in 1890, Power took up residence at Tunbridge Wells, Kent, in a house called Kilmore where Susan, who remained unmarried, kept house for him. She was a Poor Law Guardian for Ticehurst, an active suffragist and member of Tunbridge Wells Belgian Refugees Committee. In 1919, along with Amelia Scott, Power was elected as a member of the Town Council where she was the member for the West Ward. Power was active in in pressing for the appointment of women police officers. Together with Emily Jones, Power was an officer of the Tunbridge Wells branch of the Save the Children Fund and raised funds locally to feed children afflicted by the Russian famine of 1921. Power and Jones were vociferous in disputing the allegation that to donate money to starving children in Russia was to support Bolshevism. Susan Power died in October 1948 in Tunbridge Wells.
