1830 - ????
'The present day Lockridge [City of Swan, suburb of Perth] originated as part of an adjoining estate assigned to James Walcott and CD Ridley in 1830 and then purchased by Edward Hamersley in 1837. These two properties were then amalgamated and the farm called ‘Pyrton’. In 1920, part of Pyrton was surrendered to the Crown for the purpose of residential subdivision to provide war service land settlement blocks (Altone place plan 2009–2012).'
