In 1692, O'Brien entered the Irish House of Commons, sitting for Clare until 1714.
When Murrough O'Brien, 1st Earl of Inchiquin was captured Lady Inchiquin petitioned for her husband's release but Sir Donough O'Brien wrote that she had no mind to see any of his relations "for his being a papist".
Sir Donat O’Brien was son of Col. Conor O’Brien, of Leamaneagh, Co. Clare, and the notorious Mary Mac Mahon his wife (“Maureen Rhue”), who played a marked part in the rising of 1641. Conor fell in a skirmish with General Ludlow, and was brought nearly dead to Leamaneagh, 1652. Mary, as soon as he was dead, drove to Limerick, and made terms with the Parliamentary Generals, thus saving the property for her son. She is said to have married Cornet Cooper, a parliamentary officer, on the evening of the day of her husband’s (Conor) death.
After the Restoration Donat took a prominent place in Co. Clare, and represented it in Parliament, 1695 to 1713. He was created a baronet in 1686. The gateway at Leamaneagh Castle bears the tablet of his father and mother, and his own coat-of-arms with the red hand.
He died November 18th, 1717, aged 76, which shows that he was born in 1611. His will (Dublin Registry of Deeds, Book xix, p. 360) desires that “My body be decently buried in my parish church of Kileenesula, in said county, in such a manner as to my son Henry O’Brien shall seem decent and agreeable.”
