Following the self-exile of the Gaelic aristocracy in 1607, and the ensuing Ulster Plantation, it was created a second time in 1661 for the 2nd Viscount FitzWilliam, but became extinct on his death in 1667.
It was created a third time in 1685 for Sir Richard Talbot, along with the subsidiary titles Viscount Baltinglass and Baron Talbotstown, but all these titles were forfeit in 1691 when Lord Tyrconnell joined King James II against the Glorious Revolution. King James also created him Duke of Tyrconnell and Marquess of Tyrconnell in 1689, but these titles were recognised only by Jacobites (see Jacobite peerage). The forfeited earldom was claimed by Talbot's nephew, the Jacobite politician William Talbot, and his descendants.
The Earl had no surviving children. Upon his demise, and then that of his spouse, the Carpenter surname and arms Carpenter were assumed by Royal Licence, dated 1 June 1868, by The Hon. Walter Cecil Carpenter (1834 - 1904), formerly known as The Hon. Walter Cecil Talbot. He later became an Admiral in the Royal Navy.
