 William was born in Leicester House, in Leicester Fields (now Leicester Square), Westminster, London, where his parents had moved after his grandfather, George I, accepted the invitation to ascend the British throne.His godparents included the King and Queen in Prussia (his paternal aunt), but they apparently did not take part in person and were presumably represented by proxy.On 27 July 1726, at only five years old, he was created Duke of Cumberland, Marquess of Berkhamstead in the County of Hertford, Earl of Kennington in the County of Surrey, Viscount of Trematon in the County of Cornwall, and Baron of the Isle of Alderney.
