The dispute with the Earl of Ormond escalated into a long-running feud between Talbot and his brother, the Archbishop of Dublin, on the one hand, and the Butler family and their allies the Berkeleys on the other. The feud reached its height in the 1440s, and in the end just about every senior official in Ireland had taken sides in the quarrel; both sides were reprimanded by the Privy Council for weakening English rule in Ireland: the Council implored them to make up their differences. Friendly relations were finally achieved by the marriage of Talbot's son and heir to Ormond's daughter, Lady Elizabeth Butler.
