However, "The Companion to Tasmanian History" details three full-blood Tasmanian Aboriginal women, Sal, Suke and Betty, who lived on Kangaroo Island in South Australia in the late 1870s and "all three outlived Truganini". There were also Tasmanian Aboriginals living on Flinders and Lady Barron Islands. Fanny Cochrane Smith (1834–1905) outlived Truganini by 30 years and in 1889 was officially recognised as the last full-blood Tasmanian Aboriginal, though there was speculation that she was actually mixed-race. Smith recorded songs in her native language, the only audio recordings that exist of an indigenous Tasmanian language.
