In 1874, Clarke's son William built a mansion on an estate named "Rupertswood", after his own son, Rupert. The estate had access to a private railway station. Though the station was constructed in the late 19th century, the Clarkes did not pay the railways for its construction until the 1960s. (Rupertswood railway station was closed as a result of the Regional Fast Rail project and is now only a disused platform). The Clarkes also had a connection to the Kelly Gang story via their police connection with Superintendent Hare.
