Fitzgibbon was the younger son of the heavyweight former Irish lord chancellor the 1st earl of Clare, one of the architects of the Union, and the only brother of the 2nd earl, who was described in 1813 by the bishop of Limerick as being ‘without a particle of the fiery enterprising genius of his father’, but ‘a young man of much promise - a good scholar, mild and conciliatory in manner, with an excellent understanding; exceedingly popular in his county and ... a respectable nobleman’.
No evidence of parliamentary activity has been traced for that session, although on 19 Nov. 1820 Katherine Forester observed to the duchess of Rutland that ‘I am sorry to hear Mr. Fitzgibbon is such a radical. Lord Clare seems quite the contrary’.
James Abercromby* reported to the duke of Devonshire, 6 Oct. 1823, that ‘Fitzgibbon has gone off with a Mrs. Moore’, the wife of Maurice Crosbie Moore, whom he wrongly identified as a daughter of Christopher Hely Hutchinson*. Referring to Fitzgibbon’s mother, he continued
I should think Lady Clare would have a great contempt for such a proceeding. She will reasonably say, why could they not follow my example who have been doing these things all my life and have always kept my place in society. I am however very sincerely sorry for Lord Clare, who has made himself a poor man for life by struggling to return his brother for the county of Limerick and here is the end of it, I suppose.Chatsworth mss.
Fitzgibbon, who presumably absented himself from Westminster for much of the following two years, and his mistress eloped to France and her husband subsequently began legal proceedings in Dublin in June 1824 and obtained a separation in the consistorial court, being awarded £6,000 in damages. His petition for a divorce was presented to the Lords, 7 Feb., and, after conclusive evidence had been heard on 26 Apr., the Act was passed, receiving royal assent on 27 June 1825.
Fitzgibbon, who brought up several pro-Catholic petitions during the three ensuing sessions, voted for emancipation, 6 Mar. 1827, 12 May 1828, and, having been listed by Planta, the Wellington ministry’s patronage secretary, as likely to be ‘with government’, 6, 30 Mar. 1829; however, he was in the minority for Duncannon’s amendment to the related Irish franchise bill, to allow reregistration, on the 20th. He divided for repeal of the Test Acts, 12 May 1828, and Jewish emancipation, 5 Apr., 17 May 1830. He sided with opposition for reducing the salary of the lieutenant-general of the ordnance, 4 July 1828, to restrict the army grant to six months, 19 Feb., and for repealing the Irish coal duties, 13 May 1830. Clare, who was reported to be in improved spirits since his marital separation, successfully applied to be named governor of Bombay by Wellington, who commented that he ‘must be well supported [as] he had not a strong mind’, and refused him the order of St. Patrick. After some delay, he was finally elected to the post by the Company in March, with a view to travelling to India in the autumn.
He was deemed to be ‘pro-government’ in Pierce Mahony’s† analysis of the Irish elections, but, while Clare fulsomely expressed his allegiance to administration at the Company’s parting dinner in his honour in August 1830 and remained loyal to the Tories, he was listed by ministers among the ‘bad doubtfuls’, and Planta wrote beside his name that ‘he should support us - but will oppose’.
He became lord lieutenant of Limerick that autumn, despite a remonstration from Rice, the treasury secretary, who noted that he ‘cannot be invited by a single family in that county for his unfortunate marriage’.
