She was born in Cheltenham on 14 August 1877, the third of four daughters to George Cadell (1844–1909) and his wife Mary Amelia Morison McCrae (1844–1924).

In the 1920s, Cadell and her sister Agnes jointly rebuilt Whinmill Brae House in Edinburgh as an artist’s studio.
From 1956, Cadell’s close artist friend Wendy Wood came to live with her and share her Edinburgh studio at Whinmill Brae.
The grave describes her as Scottish Patriot and bears lines from verse 7 of Psalm 124, “even as a bird out of the fowler’s snare”: a reference to escaping the troubles of life.
