Oliver Plunkett, 8th Baron Louth1 
He was prevented from taking his seat in the Irish House of Lords on the grounds that he had not proved the reversal of his grandfather’s outlawry for rebellion in 1642, even though the grandfather had not been formally attainted.1 He succeeded as the 8th Baron Louth [I., 1541] in September 1689.1
