"Maude Gonne, one of the most colourful characters of Irish history, was in fact an English woman. She was born in Surrey in 1866, the daughter of an Army Colonel. Two years after her birth her father was posted to Ireland and after her mother's death in 1871 she spent her childhood between her father in Dublin and relatives in England, which she hated.

After his death in 1886 her own illness took her to convalesce in France. She had a long affair with French nationalist Lucein Milleyoye, by whom she had two children. Through him she met the old Fenian John O'Leary and she joined the Irish Republican Brotherhood. It was under Maude's spell that Yeats became a member of the Nationalist Movement.

Maude married the Boer War veteran John McBride in February 1903. They separted in 1905 after a long wrangle over custody of their only child, Sean. John McBride was executed with the leaders of the 1916 Rising, in what was regarded as more of an act of revenge by the British for his Boer War exploits. His son Sean McBride, entered the Irish political scene of the 1930's, became an International lawyer, founded Amnesty International in 1961, and had the unique distinction of winning both the Nobel and Lenin Peace Prizes.
