Sir John George Davies (1846-1913) purchased the property at public auction in March 1878 and in the early 1880s he had ornate facades in the Victorian Boom style added, although the original Old Colonial façade can still be seen behind the newer verandas.
Davies and his brothers were the co-owners of The Mercury newspaper which had been founded by their father. Davies devoted much of his time to public affairs - he was first elected to the House of Assembly in 1884 and was its speaker from 1903.
Nellie Victoria Jansen purchased Roseville in June 1926 and lived there until the mid 1940s. Jansen continued to own Roseville until 1961 but after World War II she converted it into apartments and rented them out – the 1946 Assessment Roll shows 22 people living there. Roseville remained a boarding house for many years and has only recently become a private residence once again.
