This area was named after “Londonderry”, a property of 30 acres granted to a Thomas Kendall. It is not certain if this was the same Thomas Kendall who worked as a convict labourer on the building of the same road over the Blue Mountains in 1814. It is certain, however, that the Kendall family were early settlers in the Castlereagh area, probably squatting in the area in the early 1800’s.
