Elizabeth Isabella “Betsey” Throsby (4 February 1807 – 14 January 1891) was an Australian survivor of the 1809 Boyd massacre.
Born on Norfolk Island, Throsby was two years old when she and her mother left Sydney on the Boyd, bound for England via New Zealand. During the voyage, a dispute broke out between the ship’s English captain and a Māori passenger returning to his home at Whangaroa Harbour. Once there, his tribe learned of the captain’s ill-treatment of him, and sought revenge by murdering and cannibalising most of the 70 passengers and crew, including Throsby’s mother. Throsby and three other survivors were rescued a few weeks later by merchant and explorer Alexander Berry, who took them to South America. Throsby remained there for almost a year until a whaler took her to Sydney to be reunited with her father.
She went on to marry in her late teenage years and raise a large family at Throsby Park south of Sydney, where she remained for the rest of her life.
