I whanau a George i Rānana i Norfolk House i St James's Square. Ko ia te mokopuna o Kingi George II, me te tama matamua a Frederick, Prince of Wales, me Augusta o Saxe-Gotha. I whanau ia e rua marama i mua i te wa i whanau ai ia, a, kaore i whakaarohia kia ora, i iriiria ia i te ra ano e Thomas Secker, ko ia te Kaiwhakahaere o St James's me te Pihopa o Oxford. Pātai: Ko wai tona tupuna?
Kingi Hōri II
