First Lady of the Bedchamber

In British Royal Households, First Lady of the Bedchamber is the title of the highest of the ladies of the bedchamber, those holding the official position of personal attendants on a queen or princess. The title had its equivalent in several European royal courts. The position is traditionally held by a female member of a noble family.

History
In the Middle Ages, Margaret of France, Queen of England, is noted to have had seven ladies-in-waiting: the three married ones were called Domina and the four unmarried maid of honour, but no principal lady-in-waiting is mentioned.

During the Tudor dynasty (1485–1603), the First Lady of the Bedchamber was called Chief Gentlewoman of the Privy Chamber. She had the highest rank among the Ladies of the bedchamber, and their role was to act as the attendants and companions of the royal woman. The First Lady of the Bedchamber of a queen consort was the equivalent of the post of First Lord of the Bedchamber to a king.
