It was on 4 October 1904 announced that King Edward VII had, by commission under the royal sign-manual and signet, approved the recommendation of his British prime minister, Arthur Balfour, to appoint Grey as his representative, replacing Grey's brother-in-law, the Earl of Minto. (Minto was married to Grey's sister, Mary Caroline Grey.) The appointment came at a good time for Grey, as a series of failed investments in South Africa had left him penniless; a gift from his wife's aunt, Lady Wantage (widow of the Lord Wantage), was used to supplement his salary as governor general.
