09 Feb 1915. Times Newspaper Obituaries. The news of the death of the [her former husband] Marquess of Londonderry (deceased), which occurred at Wynyard, Stockton-on-Tees, yesterday morning, will be received with profound regret far beyond the circle of his personal friends or of the members of the Unionist Party. Lord Londonderry (deceased) had not been entirely well for some little time past. For a fortnight, it seems, he had been suffering from sciatica. Last week he caught a chill, from which pneumonia developed. On Sunday his condition was seen to be critical. During the night he collapsed, and the end came at 9.30 yesterday morning. Lady Londonderry (age 58), who had been in constant attendance on him during his illness, was present at the last, as also were [her daughter] Lady Ilchester (age 38) and [her former brother-in-law] Lord Herbert Vane-Tempest (age 52).
