John Colthread's grant comprised across present-day Wharf Road. The Police Magistrate to Parramatta, Major Edmund Lockyer, purchased the land in 1827 and built the stone mansion "Ermington" - named after the parish in Devon, England, where his second wife, Sarah Morris, was born. The house was completed in 1828 and stood near the current Ryde-Parramatta Golf Course. Locker increased his land holdings and by 1830 was grazing 1280 sheep and over 300 head of cattle on more than 1900 hectares. He subdivided some of his land in 1841 and advertised it for sale as the "Village of Ermington", but not many blocks were sold. In 1843, Lockyer sold off his remaining holdings. Lockyer died in 1860. His third child by his second marriage, born in England, was named Sarah Ermington Lockyer.
