Biographical information provided by Jenni Chrisstoffels, Alexander Turnbull Library, for the He Tohu exhibition:
Cecilia Mary Lemon (nee Turnbull) was 37 years old and living in Dunedin with her painter husband, Charles Lefos Lemon, and five children, when she signed the petition. Her biggest claim to fame seems to have been for an advertisement for Clement Tonic which ran in at least 14 Otago newspapers from 1903 to 1912 and details the extreme indigestion she suffered until she started taking the tonic. She and her husband lived briefly in Invercargill and Wellington before returning to Dunedin where her husband died in 1926. She returned to Wellington and lived with her son, Charles Percy, and daughter May Margaret Adams until her death in 1946, aged 90.
