Margaret Briggs was born at Cummeragunja, New South Wales, daughter of activists Geraldine Clements Briggs and Selwyn Briggs. Her maternal aunt, Margaret Tucker, and maternal grandmother Teresa Middleton Clements were also active on behalf of Yorta Yorta rights. She had no formal high school education and instead gained much of her knowledge from seeking out the insight of government and private figures.
