In 1841 a near relation of Lord Stratford de Redcliffe's - Earl Canning, the third son of George Canning – lived at No. 10 Grosvenor Square with Lord Granville (then Lord Leveson).
Lord Canning is remembered as Governor General of India from 1855 to 1862, the year in which he died. In Henry Greville's Diary on 17th June that year, the following entry referred to the event:
"At 11 at night Sydney and I went to Grosvenor Square, where we heard that during the last three hours he (Canning) had made so great a rally that some of his family entertained hope, which, however, the doctors considered illusory. This morning Meryon called to tell me that at 6am this morning he had died."
