Mary Tyson was born on 13 Sep 1869, the youngest of six children of accountant Matthews Tyson (1835-1915) and his first wife Louise Marianne Legg. When her mother died in 1878, Mary was nine years old. Her father married Mary Ann Hart, the eldest daughter of William Hart MHA at 'Bifrons' on 9 Feb 1882. They had two children, Florence and John Leonard.
It appears that Mary never worked, and lived at 20, and later 70, Elphin Road with her father and stepmother. Mary died aged 50 on 28 Dec 1919 and was buried at the Charles Street Cemetery with her mother and sisters Annie and Louisa who both died young. Mary's brother Alfred, his future wife Ada Monds and their future brother-in-law Ernest Ritchie are also pictured in the Family Album.
