In 1856 Barr Smith married Joanna Elder, sister of Sir
Thomas Elder, also Scottish migrants to the colony.). They planned and built a 30-roomed
mansion in
French Renaissance style around the existing hotel, to be used as their family's summer home. They later assigned the name
Auchendarroch (later known as Auchendarroch House), which originates from the
Scottish Gaelic language word for "holy place of the oaks", and proceeded to plant a lot of
oak trees on the property. They assigned each for an orchard and a garden, with
hedges planted around the whole property. The garden included large lawns and many English trees, including
cedars,
chestnuts,
maples,
conifers, and around 50
oak trees. It also had flower beds and vegetable gardens, with the produce given away in the community. Barr Smith died of "
senile decay" on 20 November 1915, and Joanna died in 1919. Auchendarroch was sold in 1921 to the
Memorial Hospital and used as a
convalescent home. It was later acquired by the Wallis family, owners of
Wallis Cinemas. In 1920 his family gave £11,000 for the endowment of the library of the University of Adelaide. ==Family==
