In Australia in the early 1840s, Caroline helped single-female emigrants arriving in the colony without family, friends, money or jobs. She established a home for these young women, which was later extended to house families and young men. The home also became an employment agency, with Caroline leading large groups inland to find work. In Britain, she was tireless in her efforts to assist migration to Australia. Carole Walker's research casts new light on the life of a remarkable woman. In her day, she was a public figure as well-known as Florence Nightingale.
