About Henry FitzRoy, 1st Duke of Grafton

Lived 1663 – 1690 (aged 27). Henry FitzRoy, 1st Duke of Grafton was a British politician.

Henry FitzRoy, 1st Duke of Grafton (28 September 1663 – 9 October 1690) was an illegitimate son of King Charles II of England and his mistress Barbara Villiers. A military commander, Henry FitzRoy was appointed colonel of the Grenadier Guards in 1681 and Vice-Admiral of England from 1682 to 1689. He was killed in the storming of Cork during the Williamite–Jacobite War in 1690.

Early life and military career Born to Barbara Villiers, Countess of Castlemaine, on 28 September 1663, Henry FitzRoy was an illegitimate son of King Charles II of England, the second by Barbara Villiers. His mother was the daughter of William Villiers, 2nd Viscount Grandison, a colonel of one of King Charles I's regiments who was killed in action during the Civil War. On 1 August 1672, at the age of 8, marriage was arranged to the 5-year-old Isabella, daughter and heiress of Henry Bennet, 1st Earl of Arlington. A wedding ceremony took place on 4 November 1679 witnessed and recorded by John Evelyn in his diary of that date describing him as "exceedingly handsome, by far surpassing any of the Kings other naturall Issue". At the time of his marriage, Henry FitzRoy was created Baron Sudbury, Viscount Ipswich, and Earl of Euston. In 1675, he was created Duke of Grafton, and Charles II made him a Knight of the Order of the Garter in 1680. He was appointed colonel of the Grenadier Guards in 1681. In that year, he received a warrant to supersede Sir Robert Holmes as Governor of the Isle of Wight, when the latter was charged with making false musters. However, Holmes was acquitted by court-martial and retained the governorship. In 1686, he killed John Talbot, brother of the Earl of Shrewsbury, in a duel; Talbot having given Grafton some "unhandsome and provoking language". He was appointed Vice-Admiral of the Narrow Seas from 1685 to 1687. At King James II's coronation, Grafton was Lord High Constable. During the rebellion of the Duke of Monmouth he commanded the royal troops in Somerset. However, he later acted with John Churchill, and joined William of Orange to overthrow the King in the Glorious Revolution of 1688.

In October 1697, his widow, Isabella, married Sir Thomas Hanmer, one of Dublin's main streets. Grafton Alley in Cork, close to where he was shot, also bears his name.

Through his son, Charles, he is an ancestor of the late Diana, Princess of Wales.
