Abigail Thaw (born October 1965) is an English actress best known for her role as Dorothea Frazil in the crime drama television series Endeavour, a prequel series to the iconic drama Inspector Morse, which starred her late father.
Thaw was born in London to John Thaw and Sally Alexander in October 1965. She was brought up by her mother in a large house in Pimlico.
Alexander was an active member of the women's movement and Abigail would often go on marches with her mother and the other families in the house. She would visit her father regularly, taking trips up north to see her paternal grandfather in Manchester.
Abigail has a half-brother, Daniel (by her mother and her second husband), as well as a stepsister Melanie Thaw and her half-sister Joanna Thaw (born to John Thaw and his wife Sheila Hancock).
After graduating from school, Abigail spent a year in Italy. After her return, she went to RADA, a year behind her stepsister Melanie.
Abigail worked with her stepsister Melanie in the Royal Exchange Theatre production of Pride and Prejudice in 1991. She has also made some television appearances.
In 1997, she gave birth to her daughter Molly Mae. Shortly after Molly's birth Abigail starred in BBC1's Vanity Fair (1998).
