'Dolly Dalrymple Mountgarret Briggs was the first half-caste born in Tasmania who survived and has descendants. The daughter of an English sealer and a kidnapped Aboriginal girl, Dolly was born on one of the islands in Bass Strait in 1810. This is the story of her life, her bravery during a siege, her marriage to ex-convict Thomas Johnson and their successful life together in the pioneer frontier of the North Coast.'
