The Paget family are an Anglo-Welsh aristocratic family founded by William Paget, 1st Baron Paget (1506-1563) and now headed by the Marquess of Anglesey. The male line of the family became extinct with the death of Henry Paget, 2nd Earl of Uxbridge in 1769. The barony of Paget and the family estates passed to the late Earl's cousin Henry Bayly, 10th Baron Paget. He was the son of Sir Nicholas Bayly, 2nd Baronet, of Plas Newydd, and Caroline, Lady Bayly, daughter of Brigadier-General Thomas Paget, son of the Hon. Henry Paget, second son of William Paget, 5th Baron Paget. He assumed in 1770 by Royal license the surname and arms of Paget only. In 1784 the earldom of Uxbridge was revived in his favour. He was succeeded by his eldest son, Henry Paget, 2nd Earl of Uxbridge, the great military leader who led the charge of the heavy cavalry against d'Erlon's column during the Battle of Waterloo in 1815 and was created Marquess of Anglesey a few weeks later.
