She had five younger brothers, including politician Sir Samuel Emile Harvey.

A noted harpist and composer, she was elected a Bard of the Cornish Gorseth. In 1927, she was honorary musical director of the National Conservative Musical Union. She served as president of the Society of Women Journalists from 1929–32, and was a Member of the Celtic Congress in 1933.

She married Harry Brittain in 1905. They had two children: Robert Edmund Godefroy Brittain and Alida Gwendolen Rosemary Brittain.

She died suddenly at home in Headley, Hampshire, in 1943, aged 59.
