The Blayneys were descended from Sir Edward Blayney, a Welsh soldier who was created the 1st Lord Blayney, baron of Monaghan, in 1621. The 11th Baron, an Orangeman and army officer, Member for Old Sarum in the 1806 Parliament, retired to the family seat of Castleblayney in county Monaghan, where he exercised a minor electoral interest, in 1815.
Having seen service abroad with his regiment, Blayney retired from the army in June 1830, when he announced his candidacy for Monaghan at a dinner in his honour at Castleblayney. He based his claim on his father’s record as a landlord, but was attacked for his youth and inexperience and for failing to declare his principles during the contest, in which he took an early lead. Despite his father’s junction with Westenra, who had favoured Catholic emancipation, he struck a deal with Shirley and was elected with him as a Tory.
Westenra reported to the duke of Richmond, a cabinet minister, 3 Nov. 1831, that government
may have been told that Lord Blayney was favourable to ‘the bill’, but I can tell you that, to my certain knowledge, Lord Blayney approves of every [hostile] vote his son has given and that Mr. Blayney promised Lord Rossmore to vote for reform when he (Mr. B) canvassed Lord Rossmore for his Monaghan interest.

Early in 1832 the cabinet, who had seen through Lord Blayney’s self-serving offer of support, forced him to apologize publicly for his vitriolic attack on the supposed reduction of the household troops; the fact that a peerage was not forthcoming probably confirmed his son in opposition.
