Daughter of keen Unitarian Frederick Nettlefold and his wife Mary. Married Sydney Martineau (1863 – 1945, British Olympic fencer).
From 1929 was the lay president of the General Assembly of Unitarian and Free Christian Churches, the successor to the organisations her father presided over.
We can't find her dates but she laid the Essex Hall stone in 1957.
Do not confuse with Edith Martineau (1842 – 1909) British watercolour painter who may well have been related since she was the daughter of an eminent Unitarian minister.
