Which London district is listed as the place where Ada Lovelace died?

Ada Lovelace died in Marylebone, a district of London. Her recorded death place is commonly given as Marylebone, London, England, where she died on 27 November 1852 at the age of 36.

Lovelace had become famous for her mathematical work with Charles Babbage's Analytical Engine, but her final illness was cancer. Contemporary accounts generally called it uterine cancer because the modern medical distinction between cervical and uterine cancer was not then established in the same way.

Marylebone should not be confused with Lovelace's burial place. At her request, she was buried beside her father, Lord Byron, in the Church of St Mary Magdalene at Hucknall in Nottinghamshire. Thus, Marylebone identifies where she died, while Hucknall identifies where she was laid to rest.

The other options—Islington, Greenwich, and Chelsea—are also London districts, which makes them plausible distractors. However, the biographical record consistently gives Marylebone as her place of death.
