Roads & Streets

  • Streets names in Llandilo were given numbers as their names i.e. Ninth Avenue, Third Avenue when the area was subdivided in 1888.
  • Terrybrook Road: Named after Samuel Terry’s grant in 1831.

Origin of the place name – Llandilo

Samuel Terry (1776?-1838), an ex-convict turned rich Sydney merchant, was granted 950 acres on 13th January 1818, in the area now known as Llandilo. The property at that time however, was known as Terry Brook after the owner. Terry owned a considerable amount of land in the Castlereagh/Cranebrook area. By the early 1860s, the name Llandilo was already in limited use. When part of the Terry Brook estate was sold it was named the Llandilo Estate, and when this estate in turn was subdivided in 1888 and bought by a Mr Sullivan from Sydney, it retained the Llandilo name. Sullivan gave the streets and avenues numbers instead of names, but found it difficult to sell the bushland blocks for orchards. Indeed, the last of the blocks were not purchased until the 1930s depression. In a report to the Education Department in 1888, an Inspector stated ‘ Llandilo is the name given to an estate recently cut up into orchard blocks, and lying about four miles north of St. Marys. The whole estate is as yet practically unoccupied, the primeval bush still holds the ground…’. The name Llandilo seems to have derived from the the Welsh town of Llandeilo Fawr. Llan means church or village, and Llandeilo Fawr was the centre of the 6th century monk St. Teilo’s work and cult.
