Wells mentions how Lady Jeune supported her anti-lynching campaign by hosting a 'drawing room meeting of her friends' in her autobiography 'Crusade for Justice' (Chapter 20) During World War I, Lady St Helier befriended a Canadian ex-cavalry officer named William Avery Bishop and used her connections to speed his acceptance into flight school.

[2] In her later years, Lady St Helier resided at Poplar House in the village of Cold Ash, West Berkshire.

She donated land for the village's parish room, an early form of community centre, which opened in 1911.

[4] She wrote at least 50 periodical essays, which challenge the idea that Victorian middle and upper-middle class women were not capable of serious nonfiction writing.

[citation needed] Lady St Helier appears as a character in the Canadian stage musical Billy Bishop Goes to War.
