Ultimately descended from the great medieval chieftain Brian Boroimhe (Boru), O’Brien’s cadet branch of this ancient Clare family sprang from a younger son of Morrough O’Brien, who surrendered the kingship of Thomond to Henry VIII in 1543 and whose eldest son was the ancestor of the marquesses of Thomond.
He is squat, bluff and impassioned. An expression of good nature, rather than good humour, is mixed up with a certain rough consciousness of his own dignity, which in his most familiar moments he never lays aside, for the Milesian predominates in his demeanour and his royal recollections wait perpetually upon him. He is a great favourite with the people, who are attached to the descendants of the ancient indigenous families of the county and who see in Sir Edward O’Brien a good landlord as well as the representative of Brian Boru.

While not sharing the exasperating piety of his wife, who busied herself with supporting local Protestant schools, he devoted himself to the promotion of his estates, the rebuilding of Dromoland and his family’s parliamentary ambitions.
A life-long supporter of Catholic relief and a ministerialist since 1807, he was an almost silent supporter of Lord Liverpool’s Tory government, though he had occasion to resent its neglect of his demands for county patronage.
Writing en route to England, 29 Apr. 1820, O’Brien consoled his wife, who hated to be separated from him, that ‘I shall either remain at home next year or take you with me and after that I shall take the matter very easy, whether I ever attend Parliament or not’. On 9 May he wrote to her that
I am sure I shall never be able to give a close attendance in the House of Commons again. Indeed I entered it yesterday without a single feeling of either interest in the proceedings or pleasure at finding myself in a situation, the ambition of so many and the cause of such immense expense.
He was obliged to remain in London to divide with ministers that month, though on the 16th he informed his wife that, as he did not like the defence made by the lord advocate over the appointment of an additional baron of exchequer in Scotland, he had left the House before the division on this the previous night.
Having journeyed as far as Leicester, 28 Feb. 1822, he decided that the persistence of a cold would preclude his parliamentary attendance and so returned to Ireland. During the following two months he stayed at Dromoland, conscientiously and humanely assisting with local relief efforts, a duty which he judged to be incumbent upon him as a resident country gentleman, and corresponding with ministers about the devastating effect of the prevailing famine.
O’Brien probably missed the 1823 session as in early May Lucius, who was hoping that his father would soon fulfil his promise to relinquish his seat to him, reported to a friend that he ‘has been prevented going to London hitherto by the state of his health which has been very precarious from liability to inflammation in the chest’.
From Dromoland, he wrote to Canning, the foreign secretary, 28 Oct. 1825, that having for the previous 20 years ‘given a liberal and independent support to His Majesty’s ministers’, he would welcome government’s endorsement of his plan to return Lucius for Clare and his second son William for Ennis at the next election:
The politics of myself and my sons being in perfect unison with the liberal and enlightened views you have uniformly advocated both in and out of Parliament, I have thought it not unbecoming me to state these circumstances and to point out how you may attach two young independent men to your interest in the new Parliament.

Declining to attend Daniel O’Connell’s* dinner to the Friends of Civil and Religious Liberty early the following year, he emphasized his ‘uniform and zealous support’ for Catholic claims.
Although, perhaps because of his money worries, O’Brien nominated the ministerialist Thomas Frankland Lewis at Ennis, he secured the unopposed return of Lucius for Clare at the general election of 1826, and he was thanked for his exertions in their cause by the Catholics of his county at a meeting that summer.
Despite a rumour that O’Brien would stand himself, he again put forward the ineffective Lucius for Clare at the general election of 1830. As provost, he oversaw William’s re-election for Ennis, but illness forced his retreat from the proceedings at the county election and a few days into the poll, which Lucius lost, he was refused permission to enter the contest as a security for him.
In spite of his failing health, O’Brien more or less completed the rebuilding of Dromoland and, having predicted that year that he would expire at the same age as his father (64), he died, murmuring ‘His mercy endureth forever’, in March 1837, when his title and estates were inherited by Lucius.
