Mary Wolverston, Lady Killigrew, was a gentlewoman from Suffolk, married into an ancient Cornish family, who was accused of piracy during the reign of Queen Elizabeth I. Several sources have confused this lady with her husband Sir John IV Killigrew's mother Elizabeth Trewennard/Trewinnard and even with his granddaughter-in-law Jane Fermor.
Origins
She was the daughter of Philip Wolverston of Wolverston Hall in Suffolk, and widow of Henry Knyvett.
She and her husband received and stored stolen goods at their home, Arwenack House. In 1582, she was arrested and sentenced to death after she sent her servants to seize the cargo aboard a ship anchored opposite Arwenack House, later the nucleus of the 17th century town of Falmouth.. Queen Elizabeth eventually pardoned her, and she was released from prison. Mary was also known as "Old Lady Killigrew".
Piracy
In the 1540s Pendennis Castle was built by King Henry VIII on part of the Arwenack estate belonging to the Killigrew family. Mary's father-in-law John III Killigrew was appointed by the king as the first hereditary Governor of Pendennis Castle, and after his death Queen Elizabeth I appointed as second Governor his son Sir John IV Killigrew. The Governorship allowed control to be exerted of all of the shipping in the Carrick Roads harbour, and along part of the south coast. Sir John IV Killigrew used his privileged position to prey on the cargoes of the ships that came within his reach. In 1567 Arwenack House was fortified as a stronghold and used to store merchandise stolen in raids on ships. Mary and her husband paid large fees to officials, bribing them to allow their illicit activities. Mary played an active role in the piracy, and apparently enjoyed the adventure more than her husband. Historian Neville Williams described Mary as a "tough and unprincipled businesswoman" who managed Arwenack House and oversaw the burial of treasure in her garden. In January 1582 Mary, by that time in her 60s, heard a rumour that there was treasure aboard the Spanish ship Marie of San Sebastian anchored opposite Arwenack House, and she sent her servants to seize the ship and search the cargo. Despite rumours to the contrary, it seems unlikely she ever personally went on a raid; however she was arrested for having received and fenced stolen goods after the seizure of Marie of San Sebastian during which a factor was murdered when the ship was boarded by her raiding party. Some of her family members were included in the accusation. Mary was brought to trial and sentenced to death. Though two of her assistants were executed, she eventually received a pardon from Queen Elizabeth I. Mary's son secured her release from prison after having paid substantial bribes.
Death
Mary died on an unknown date in the parish of St Budock, Cornwall, in which was situated Arwenack. She was still alive in 1587, when her son John was accused of hindering further legal proceedings for piracy against her.
In fiction
The identity of Mary Killigrew is often confused with her mother-in-law Elizabeth Trewinnard in derivative sources and fictional works. Lady KiIligrew is arguably the dominant character in the historical novel The Grove of Eagles by Winston Graham. Her grandson, who narrates the novel, describes her as a woman of insatiable greed and desire for power, "she knew all she wanted and wanted all she knew". Another character condemns her as "that harsh and evil woman". Her husband appears in Rafael Sabatini's The Sea-Hawk as well as in a series of German sea-adventures "Seewölfe, Korsaren der Weltmeere". He is usually depicted as a villain.
Progeny
By her husband Mary had the following progeny:
John V Killigrew, Esquire, of Arwennack, eldest son and heir, MP, 3rd Governor of Pendennis Castle. who married Dorothy Monck, a sister of General George Monck, 1st Duke of Albemarle, by whom he had issue.
Several sources have confused this lady with Sir John IV Killigrew's mother Elizabeth Trewennard/Trewinnard and even with his granddaughter-in-law Jane Fermor. The primary source for this famous story, which has been much added to and embroidered by several writers, is:
Calendar of State Papers, Domestic, 15 January 1582 & 2 March 1582, which is a record of the official enquiry.
Whitley, H. Michell, Journal of the Royal Institution of Cornwall, Vol.VII, 1881-3, pp. 282–7, Dame Killigrew and the Spanish Ship, re account of piracy of Mary Wolverston, wife of Sir John IV Killigrew. This is the most reliable account, and lists inaccuracies of Hals's account. Followed by Baring-Gould.
The most reliable pedigree of the Killigrew family is:
Vivian, Lt.Col. J. L., The Visitations of Cornwall: Comprising the Heralds' Visitations of 1530, 1573 & 1620; with additions by J. L. Vivian, Exeter, 1887, pedigree of Killigrew, pp. 267–71
