Anne was estranged from her brother-in-law and cousin, William III, and her sister, Mary II, but supported links between them and her son. He grew close to his uncle William, who created him a Knight of the Garter, and his aunt Mary, who frequently sent him presents. At his nursery in Campden House, Kensington, he befriended his Welsh body-servant, Jenkin Lewis, whose memoir of the Duke is an important source for historians, and operated his own miniature army, called the "Horse Guards", which eventually comprised 90 boys.
