Lucy Edgar was the daughter of Francis Smith Edgar and his wife Harriet Elizabeth. Francis Edgar was a trustee and active member of the Hobart Particular Baptist Chapel in Harrington Street, Hobart. Lucy was also active in the Sabbath School.
Ian Morrison (q.v.) and Laurie Rowston (q.v.) argue that Lucy Edgar used the pseudonym 'Theresa Tasmania'. Rowston maintains that the identification of Lucy Edgar with Theresa Tasmania can be seen as definitive. The two authors are linked by an editorial note in the Tasmanian Messenger November 1865 and the poems published in Tasmanian publications of the period support this identification through their religious themes, reflecting the Baptist faith of Lucy Edgar.
