Mary Louisa, known as “Lou”, was born at Pinkerton Plains on 11 August, 1871. Her sister, Lillian Elizabeth, known as “Lil”, was born at Stockyard Creek on 3 April, 1874. Both women remained unmarried, and according to their nieces, it was the wish of their mother Mary Ann that they do so. Several proposals were politely turned down, by all accounts. Lou and Lil lived with their parents at “Pine Farm", and after the death of their mother and the remarriage of Thomas and his subsequent removal to Brighton in 1915, they also moved to Adelaide where they bought a house in Dunnrobin Road, Hove.

A niece of these two ladies, Elia Fyfe, remembers her Aunt Lil when she attended the Owen school. Catching the train for Owen at Stockyard Creek meant calling in on her grandparents Thomas and Mary Ann at “Pine Farm" on the way home to “Boundary Farm” and being driven home by Aunt Lil and her grandmother.

Lou outlived her younger sister by six years and died in the South Glenelg Hospital on 4 June, 1952, aged 81 years. Lil died at home (Dunrobin Road, Hove) in April, 1944, aged 70. Both are buried at the same cemetery as their father at Brighton, behind St. Jude’s Church of England.
