George Augustus Hamilton Chichester, 5th Marquess of Donegall was an Anglo-Irish soldier and company promoter who became an Irish and British peer, with a seat in the House of Lords. In his youth he was an officer of the 6th Regiment of Foot by purchase and a director of railway companies. He was made bankrupt in 1866 and died in reduced circumstances, after inheriting his peerages in 1889. After being widowed in 1901 he advertised that he was willing to marry again for £25,000 to be paid to himself and in the last year of his life finally succeeded in gaining a son and heir.
After the Matrimonial Causes Act 1857came into force, Chichester appeared at least three times in the new Divorce Court. He was co-respondent for adultery in the case of Lloyd v. Lloyd and Chichester, and again in Mure v. Mure and Chichester. On 1 July 1859 the court granted a decree to dissolve the marriage of the Mures, and on 9 August Chichester married Mrs Mure, but in 1863 he successfully applied to the court for this marriage to be declared void, bringing an action against "Virginia Elizabeth Mure, falsely called Virginia Elizabeth Chichester", on the grounds that no divorcee could remarry within three months of the decree. The Spectator drily called this "a fact which Mr. Chichester, with his large experience in such cases, would, one would think, have known", and added that "the case is just one of those which create the vulgar belief that the class to which Mr. Chichester belongs is exceptionally immoral."
On 31 August 1865 Chichester married secondly Mary Anne Williams Cobb, the youngest daughter of Edward Cobb, of Arnold, Kent, and Kensington. The marriage was childless, and his wife died in November 1901, her final address being 7, Upper Rock Gardens, Brighton. Probate of her will was granted to Alice Cobb, widow, and all of her property was valued at £43. In February 1902, weeks after the death of his second wife, Donegall advertised in The Daily Telegraph for a lady "willing to purchase the rank of a peeress... for twenty-five thousand pounds sterling, paid in cash to her future husband, she must be a widow or a spinster—not a divorcee." Country Life later commented that this "scarcely suggests a fairytale romance" and described Donegall as "an old roué", continuing "May one speculate on the appropriateness of the Donegall coat-of-arms? The supporters are two red wolves held in chains of gold." On 23 December 1902, by now aged eighty, Lord Donegall married thirdly Violet Gertrude Twining only daughter of Henry St George Twining, a banker of Halifax, Nova Scotia, and Coombe Oak, Kingston Hill, Surrey, and they had one child, Edward Arthur Donald St George Hamilton Chichester, born on 7 October 1903, who became Marquess of Donegall when his father died on 13 May 1904. Donegall, whose address at death was 117, Cromwell Road, Kensington, died at 42, Norfolk Road, Brighton, leaving an estate valued at only £27. His widow died on 8 October 1952, at the age of 72. His infant son Edward grew up to become a journalist and war correspondent.
