I enjoyed reading the information provided at your website compiled by T.A. Johnston on pioneers in your area, with emphasis on the Ruledge Family, particularly Thomas Rutledge. I have a scan of the front and reverse of an envelope sent to Mrs Rutledge from Bungendore routed through Goulburn to Cambelltown, and thence to Parramatta, and presumably to Brush Farm near Eastwood. Eastwood P.O. did not open until 1.11.83 so there was no Eastwood postmark, and Brush Farm also had no P.O. There was no letter enclosed.
