Raleigh was born to a Protestant family in Devon, the son of Walter Raleigh and Catherine Champernowne, and a cousin of Sir Richard Grenville and younger half-brother of Sir Humphrey Gilbert. Little is known of his early life, though in his late teens he spent some time in France taking part in the religious civil wars. In his 20s he took part in the suppression of rebellion in the colonization of Ireland; he also participated in the siege of Smerwick. Later, he became a landlord of property in Ireland and mayor of Youghal in East Munster, where his house still stands in Myrtle Grove. He rose rapidly in the favour of Queen Elizabeth I and was knighted in 1585. He was granted a royal patent to explore Virginia, paving the way for future English settlements. In 1591, he secretly married Elizabeth Throckmorton, one of the Queen's ladies-in-waiting, without the Queen's permission, for which he and his wife were sent to the Tower of London. After his release, they retired to his estate at Sherborne, Dorset.
