The story is a good one. Lady Anne was born in 1837 and died, in Egypt, in 1917. Her mother, Ada, who was connected with Babbage and his prototype computer, was Byron’s only legitimate child. Aged 32 and wealthy, Lady Anne was plucked off the shelf by the poet and philanderer Wilfrid Scawen Blunt. After miscarrying several times, in 1873 she gave birth to their only living child, Judith, later Lady Wentworth. The Blunts then set out on their Arabian adventures, she being the first European woman to cross the northern desert. They met real danger and hardship. Winstone is excellent on these journeys, which undoubtedly had a profound cultural influence on Lady Anne. He says, and the notion is credible, that her name (but not Wilfrid’s) continues to have a historical resonance in parts of Arabia.
