Born in London, she was one of the three children of John Biker and Frances Ann Farmer. The artist was home-schooled, and was taught art by her brother, Alexander Farmer, who was a genre painter. She began her career painting miniatures, two of which where exhibited at the Royal Academy in 1847 and 1849. However, from 1850 she began to specialise in genre paintings, most of which depicted children in rustic settings. Works such as Kitty’s Breakfast (1883), and In Doubt (1881) are both definitive of her subtle and intuitive style. (Both these works are on display at the Victoria and Albert museum). In 1854 she was elected as a member of the New Society of Painters in Watercolours, to whose exhibitions she contributed ninety-six paintings over a fifty year period. She also exhibited works at the Liverpool Academy and the Royal Scottish Society of Painters in Watercolour. During this time in her life, she lived at Portchester, Hampshire, where she eventually died in 1905.
