Marylebone (via Wikipedia):
Marylebone gets its name from a church dedicated to St Mary, represented now by St Marylebone Parish Church (1817); the original church was built on the bank of a small stream or "bourne", called the Tybourne or Tyburn. This stream rose further north in what is now Swiss Cottage, eventually running along what is now Marylebone Lane, which preserves its curve within the grid pattern. The church and the surrounding area later became known as St Mary at the Bourne which, over time, became shortened to its present form, Marylebone. It is a common misunderstanding that the name is a corruption of Marie la Bonne (French for "Marie/Mary the good"). […]

Bentinck Street leaves Welbeck Street and touches the middle of winding Marylebone Lane. Charles Dickens lived at number 18 with his indebted father (on whom the character Wilkins Micawber was based) while working as a court reporter in the 1830s, and Edward Gibbon wrote much of The Decline and Fall of the Roman Empire while living at number 7 from the early 1770s. James Smithson wrote the will that led to the foundation of the Smithsonian Institution while living at number 9 in 1826, while number 10 was briefly graced by Chopin in 1848, who found his apartment too expensive and moved to Mayfair.
