Report in the Sheffield Independent 27 March 1919 finally confirming Lord Grosvenor's death

"OCTOBER '14 TO MARCH '19

Lady Hugh Grosvenor whose husband's death is now officially concluded to have taken place in October 1914, when he was listed as 'missing' along with her brother, Lord Crichton, had long ago abandoned all hope of his being alive. In October 1917, as nothing had been heard of him, Lady Hugh after three years of anxiety, was reluctantly compelled to believe he was no more. She then resigned his prospective candidature for Macclesfield. He was the Duke of Westminster's step-uncle."
