Dorothy Percy, Countess of Northumberland (formerly Perrot, née Devereux; c. 1564 – 3 August 1619) was the younger daughter of Walter Devereux, 1st Earl of Essex by Lettice Knollys, and the wife of Henry Percy, 9th Earl of Northumberland.
Dorothy was born in about 1564, the daughter of Walter Devereux, 1st Earl of Essex and Lettice Knollys, a lady-in-waiting of Queen Elizabeth I of England. Her paternal grandparents were Sir Richard Devereux and Dorothy Hastings, after whom she was named. Her maternal grandparents were Sir Francis Knollys and Lady Catherine Carey, the daughter of Mary Boleyn, herself the sister of Queen consort Anne Boleyn. Dorothy had an elder sister Penelope Devereux, who was said to have been the inspiration for Sir Philip Sidney's sonnet sequence Astrophel and Stella. She had three younger brothers, Robert Devereux, 2nd Earl of Essex, Walter Devereux and Francis Devereux.
In September 1576, Dorothy's father died in Dublin, Ireland of dysentery. Two years later, her mother married secondly and in secret, Queen Elizabeth's favourite Robert Dudley, Earl of Leicester, thus earning the wrath of the queen, who promptly banished her from court. The marriage produced one son Robert, Baron Denbigh who was born in 1581. The boy died at the age of three. In 1589, eleven months after Leicester's death, Dorothy acquired another stepfather, Sir Christopher Blount, who was thirteen years younger than her mother. On 25 February 1601, her brother Robert, 2nd Earl of Essex was beheaded at the Tower of London for treason.
In July 1583 at Broxbourne Hertfordshire she married Sir Thomas Perrott, 1st Baronet of Haroldston. There were rumours at the time that Dorothy's father-in-law, John Perrot, was an illegitimate son of Henry VIII by his mistress Mary Berkeley. They had three daughters:
Dorothy married secondly in 1594, Henry Percy, Earl of Northumberland, known as "The Wizard Earl", but the marriage was not a success, and they later separated. In 1605, the earl was sent to the Tower of London on suspicion of involvement in the Gunpowder Plot, and he was not freed until after his wife's death.
They had four children:
Through her eldest daughter Dorothy, Countess of Leicester, she was an ancestress of Diana, Princess of Wales.
