This is the story of Leandro Illin and his family who settled in Australia in 1910 after roaming the world seeking a new home. Five years later, in the face of official opposition, Leandro married a Ngadjon Aboriginal woman, Kitty Clarke. Following her death in 1925 he raised their six children by himself in outback Queensland, struggling to eke out a living in the bush. Part biography, part history and part detective story, My Dark Brother is a fascinating book about an extraordinary family.
