History Colonial history As early as 1817 retired army officer Lieutenant Samuel North was granted south of Parramatta and south of today's suburb of Guildford. He named his property Guildford in honour of the Earl of Guildford. An area of west of Woodville Road was reserved by Governor Phillip and then passed to the Church and Schools Corporation. John Thomas Campbell, administrative assistant to Governor Macquarie in 1823 also received a grant of of land. Campbell's land which he called "Quid pro Quo", lay west of Woodford Road and south of Rawson Road. William and John Lackey also received grants in the area in 1838. Their property was known as Woodville. Then in 1843 Henry Whitaker purchased North's Guildford property along with several neighbouring properties and called his land Orchardleigh. The Quid pro Quo estate was subdivided for sale into four blocks in 1832. Additional subdivisions occurred in the 1860s and 1870s with land being purchased by Holroyd and Sherwin. Phillip's reserved area was subdivided in 1871. By 1870 a small settlement had developed with a school at William and John Lackey's Woodville and by 1880 a church had been erected. In 1876 a railway station opened to the north, west of Woodville Road and at the west end of today's Guildford Road. As a new settlement began to develop around the railway station, the earlier settlement became known as "Old Guildford". Near the railway station the land of Stimson was subdivided in 1876 and 1884 and the new settlement of Guildford emerged. It was not until 1913 that Guildford began to grow into a busy town. A brickworks established in 1915 and the subsequent building industry contributed to its growth. New shops and houses were built for the increasing population. While the building boom lasted into the 1920s, a 1928 aerial photograph shows that much of the surrounding region was still undeveloped.
