In the early days of settlement Tahmoor was known as Myrtle Creek and Bargo West or for a short time Cordeaux. It was a farming area on the great Southern Road, later renamed the Hume Highway. Myrtle Creek derived its name from the myrtle trees which grew along the creek flowing through the area.
In 1892 residents petitioned, via the Thirlmere Progress Association for its own post office at “the junction of the main southern road with the Thirlmere and Pot Holes Roads”. The road to Thirlmere was then via Bronze wing Street.
On July 28 1916 the Postmaster General was advised that the Chief Railway Commissioner suggested Tahmoor as a suitable name. The name Tahmoor is believed to come from the Aboriginal name for the Bronzewing Pidgeon. After the naming in 1916 several land subdivisions were made between 1917-1922. Many of the streets have names associated with Sydney- George, Market, King , Castlereagh while others celebrate local identities such as Emmett and Larkin.
The Main Southern Railway lined opened in 1919, it included a railway station named Tahmoor which opened on 13 July that year. The name was contested by a local businessman who wished to establish a town called Bronze wing Park, but his claim was rejected.
