Olivia Gwyneth Zoe FitzRoy,[1] (27 May 1921 – 24 December 1969) was a British author of children's books.
She was the granddaughter of Muriel FitzRoy, 1st Viscountess Daventry, raised to the peerage as widow of Edward FitzRoy, the Speaker of the House of Commons from 1928 until his death in 1943; her mother was a member of the famous Guinness family.
They were there in 1939 when her father, a naval officer, decided that they should remain in Inverewe for the duration of World War II.
The area was remote; FitzRoy wrote her first book, Orders to Poach (which told the story of the Stewart children receiving unusual instructions from their overseas father) to entertain her two younger sisters, Barbara (now Ormrod) and the late Amelia (now Jessel).
After the war, she travelled with the 'Chipperfield Circus', which was the inspiration behind Wagons and Horses; she then went back to live in Scotland.
