As the wife of a politician, judge and later Lieutenant-Governor of Tasmania and mother of five children, she devoted much of her time to charitable causes, one of which was the Red Cross Society. She was appointed Officer of the Order of the British Empire in 1918 for her services to the Red Cross Society.
