Eden’s father, the brother of William Eden, 1st Baron Auckland, served with distinction in a succession of diplomatic postings before retiring as ambassador to Austria in 1799, with an Irish peerage and a pension of £2,000 per annum.
One leading Tory found Eden to be ‘an agreeable man’, but Peel’s professed ‘conviction that a new avenue of distinction’ had been opened to him proved unfounded, as he made little mark in the House.
In December 1830 Eden succeeded his father to the Irish peerage and the main family property at Watford, near Daventry, Northamptonshire.
my fortune and pretensions are not such as to justify a claim to the full extent of the honours of my grandfather and uncle. But the inheritance which I have received from them through my mother, with my private fortune derived from other sources, are such as to entitle me to affirm that they are sufficient to support both in my own person and in that of my descendants the rank of a baron.Ibid. Henley to Brougham and Grey, 8 Apr. 1831.
In 1832 he made a considerable impact with his Plan of Church Reform, which called for ‘a timely and judicious correction of abuses’ and went quickly to eight editions. He wished to eradicate pluralism, non-residence and sinecures, redistribute church revenues and create new sees. Most controversially, he suggested the establishment of a commission, partly salaried, to manage episcopal property. The scheme infuriated many churchmen and provoked a lively response. Henley, for his part, repeatedly pressed Brougham to persuade ministers of the need for action, and in September 1832 he formed the Church Reformation Society, of whose provisional committee he became chairman. His ideas were in close accord with those of Peel, whose ecclesiastical commission of 1835 proceeded on broadly similar lines.
Henley had by no means a bad chance of success ... [but his] want of spirit saved his adversary. He is not qualified for a popular election. He is very gentlemanly and by no means without talent, and he has a fine person - tall and well-proportioned - but he is entirely without the art of public speaking, and he is singularly indecisive ... He is best adapted to private life. An excellent husband and father, and a kind friend, he has effaced the recollections of a very irregular youth by years of active benevolence and virtue.Brougham mss, Henley to Brougham, [?20 Oct.]; The Times, 9, 16, 22, 24 Nov., 15 Dec. 1832; Three Diaries, 286-7.
During 1840 it became apparent that Henley was insane, and he was relieved of his duties as a master in chancery. He died in February 1841 and was succeeded by his elder son Anthony Henley (1825-98), Liberal Member for Northampton, 1859-74, who received a United Kingdom peerage as Baron Northington in 1885; his personalty was sworn under £30,000.
