Williams married twice. At Oxford she met
Peter Parker (the future head of
British Rail) and they had a relationship. In her autobiography (
Climbing the Bookshelves) Williams said that "...by the spring of 1949 I was in love with him, and he, a little, with me...". In 1955, she married the moral philosopher
Bernard Williams. Bernard left Oxford to accommodate his wife's rising political ambitions, finding a post first at
University College London (1959–64) and then as Professor of Philosophy at
Bedford College, London (1964–67), while she worked as a journalist for the
Financial Times and as Secretary of the Fabian Society. The marriage was dissolved in 1974; Bernard Williams subsequently married Patricia Skinner and had two sons with her. Shirley said of her marriage to Bernard: ... [T]here was something of a strain that comes from two things. One is that we were both too caught up in what we were respectively doing — we didn't spend all that much time together; the other, to be completely honest, is that I'm fairly unjudgmental and I found Bernard's capacity for pretty sharp putting-down of people he thought were stupid unacceptable. Patricia has been cleverer than me in that respect. She just rides it. He can be very painful sometimes. He can eviscerate somebody. Those who are left behind are, as it were, dead personalities. Judge not that ye be not judged. I was influenced by Christian thinking, and he would say "That's frightfully pompous and it's not really the point." So we had a certain jarring over that and over Catholicism. In 1987 she married the Harvard professor and presidential historian
Richard Neustadt, who died in 2003. She had a daughter with Bernard Williams, a stepdaughter, and two grandchildren. Her daughter, Rebecca, became a lawyer. She was a longtime resident of Hertfordshire, living in
Furneux Pelham after she was elected MP for Hitchin, and moving to
Little Hadham,
Hertfordshire later in life, before spending the final year of her life in a care home. Williams was a
Roman Catholic and, from 2009, attended church every Sunday. In
''Who's Who'', she listed her recreations as "music, poetry, hill walking". Liberal Democrat leader
Ed Davey called Williams a "Liberal lion and a true trailblazer" and stated that "political life will be poorer without her intellect, her wisdom and her generosity". == Honours ==
