 The house could not be donated directly by the Onslows, so the Earl arranged for his aunt, Gwendolen, Countess Iveagh, the daughter of William Hillier, 4th Earl of Onslow and a former MP herself, to purchase Clandon House from the Onslows for £1.The National Trust would only accept the house if it also received a substantial monetary endowment.This was arranged, and Clandon House with seven acres of land – including Hinemihi – were donated to the National Trust.
