Harriett (Hettie) Wheeldon, the daughter of Alice Wheeldon and William Wheeldon, a commercial traveller, was born in Bootle on 25th February 1891.Ten years later Hettie and her family moved to 91 Stanhope Street, Derby where her mother ran a second-hand clothes shop at 12 Pear Tree Road. The Derby & District Directory records that she bought and sold the contents of people's wardrobes.
Alice Wheeldon became active in politics. She was a socialist and a member of the Socialist Labour Party (SLP) . She was also active in the Women's Social and Political Union (WSPU).
Hettie and her sister, Winnie Wheeldon, shared their mother's political views. The sisters both attended the British and Foreign School Society's Teacher Training College in Lambeth. Both women became friends with Jimmy Thomas, the Labour Party MP for Derby. Hettie eventually found work as a teacher in Ilkeston and was described as having "advanced revolutionary tendencies." She told a friend that she was convinced that they were observing the "convulsive death rattle of capitalism". Hettie was also an atheist who had a strong dislike of Christianity. In a letter to a friend she remarked: "I'm not a Christian, therefore not a hypocrite".
The outbreak of the First World War caused conflict between Hettie and the WSPU. Hettie was a pacifist and disagreed with the WSPU's strong support for the war. Sylvia Pankhurst and Charlotte Despard established the Women's Peace Army, an organisation that demanded a negotiated peace. Hettie, Alice Wheeldon and Winnie Wheeldon, all joined this new political group. Other members included Helena Swanwick and Olive Schreiner.
Alice and her daughters also joined the No-Conscription Fellowship (NCF).
