Stephen Duck and Queen Wilhelmina Charlotte Caroline (Caroline of Ansbach)
"In early October 1730 Duck travelled to Windsor to be presented to the queen. ... Duck was well received by the queen, who gave him an annuity of £30 or £50 and a house. In 1733 she made him a yeoman of the guard, and in 1735 keeper of the queen's library in Merlin's Cave, a Gothic building in Richmond Gardens, a post he filled with diligence and taste." (ODNB)
