Count de Rossi was born Francis Robert Lewis Rossi in 1823 at Port Louis, Mauritius. His father, Francis Nicholas Rossi, accepted the post of superintendent of police in New South Wales, offered him by Earl Bathurst, in August 1824. In 1828 Francis purchased land near Goulburn NSW, calling it 'Rossiville'. In 1896 Francis Robert obtained his grandfather’s title of comte de Rossi, following the death of the then Count in France.
