The Viscountcy of Valentia was held by the Earls of Anglesey from 1661 until 1751, when on the death of 6th Earl of Anglesey, 7th Viscount Valentia, there were contradictory decisions by the English House of Lords and the Irish House of Lords on the validity of the 6th Earl's marriages. He had issue only by his third marriage. The Irish House of Lords accepted the validity of this marriage and consequently his eldest son by that marriage, Arthur Annesley, was allowed to succeed as 8th Viscount Valentia. However, the English House of Lords were of a contrary opinion and, rejecting the validity of the third marriage, declared the Earldom of Anglesey to have become extinct.
