She was born in 1926, her father was Jacob Epstein, the sculptor, and her mother was Kathleen Garman. Her father was married and he would visit her mother in Chelsea between 6 and 7 pm each day. Her mother lived a Bohemian life that was considered unsuitable for bringing up her children. Kitty went to stay with her grandmother in Herefordshire and her elder sister was also looked after. Her grandmother and her partner Toni Thomas became her bibliophile guardians and Margaret's daughters Lorna and Ruth were her role-models. Her aunt Lorna left her first husband to have an affair with Laurie Lee and then with Lucien Freud as well. Lorna dumped Lee and eventually Freud as well because of his unfaithfulness with other men and women. Kitty studied at the Central School of Arts and Crafts under the tuition of Bernard Meninsky and was taught book illustration by John Farleigh. Once she was introduced to Lucian Freud at the Café Royal her own artistic studies took a back seat. Freud had previously been the lover of Kitty's aunt, Lorna Wishart, who introduced Freud to her niece. Their five-year relationship was turbulent, and became increasingly unstable due to Freud's alleged infidelities and womanising, which took their toll on Kitty's health. They had two children, Annie Freud in 1948 and Annabel Freud in 1952. The same year Kitty left Freud and went to live with her parents after Freud started at another affair with Lady Caroline Blackwood. Her elder brother Theodore Garman was a talented painter, who suffered from schizophrenia and died suddenly aged only 29 in 1954, and her younger sister Esther took her own life in the same year. Her own parents eventually married in 1955, after the death of Epstein's first wife Margaret. In 1955 Kitty married the musician and economist Wynne Godley. Her second husband had studied at the Paris Conservatoire and he became principal oboist at the BBC Welsh Orchestra, but his career was ended by his own stage-fright. Her father used her husband's "impossibly handsome" head as the model for his statue of St Michael at the rebuilt Coventry Cathedral. Wynne Godley would become a leading economist noted for his unheeded warning of global recession. She and her husband had a child, Eve, in 1967. Kitty continued to draw and paint throughout her life and took an active interest in the Walsall gallery until her death. An exhibition of her work was held at the gallery in 2004. Godley suffered from dementia in her last years and died in 2010.
