What was the name of James Bond's secretary in Ian Fleming's novels from 1955 until 1963?

Loelia Ponsonby, nicknamed 'Lil', was a fictional Principal Secretary of the 'Double-O' ('00') Section, an ultra-covert Black Ops unit within the British Secret Service. She acted as James Bond's shared personal secretary in several of Ian Fleming's novels from "Moonraker" (1955) until "On Her Majesty's Secret Service" (1963) and subsequently appeared in period continuation novels "Devil May Care" (2008) and "Trigger Mortis" (2015).

Introduced in "Moonraker", Loelia Ponsonby works in the Double-O Section office on the eighth floor of the Secret Service headquarters in London. She is described as "tall and dark with a reserved, unbroken beauty to which the war and five years in the Service had lent a touch of sternness". A motherly figure to the Double-O agents, Ponsonby was the secretary to 007, 008 and 0011. Often the object of their romantic advances, Ponsonby had no intention of becoming emotionally involved with any man with such a short life-expectancy.
