Born at her family's Castle Howard, she worked for the ordination of women, as well as being active in the ecumenical movement. She was remembered as "a great character, a great Christian woman and a formidable person" by the Archdeacon of York, George Austin, who was one her staunchest opponents on the ordination of women. Her grandmother, Rosalind Howard, Countess of Carlisle, had been a tireless worker for the women's suffrage organization - as a suffragist, wedded to legal means, rather than a suffragette - and Howard followed her example in her work to achieve the ordination of women to the priesthood. ^{[citation needed]}

A founding member of the Movement for the Ordination of Women, she concentrated her major effort on the synodical process to secure the necessary legislation. In 1972 she wrote a report for General Synod entitled The Ordination of Women to Priesthood. She earned the Lambeth Diploma in Theology, was appointed a lay canon provincial of York Minster, served on General Synod 1970–85, was a delegate to the World Council of Churches (WCC) in 1961 and 1968, was appointed to the Faith and Order Commission of the WCC and served as the first woman vice-moderator. ^{[citation needed]}
