The area occupied by St Felix de Valois Parish was originally known as Irishtown on account of the large number of people of Irish extraction who lived there. While occupation of the district goes back to the earliest days of European settlement of the colony, little is known about the religious life of the inhabitants until 1839 when the area came under the jurisdiction of the newly formed parish at Liverpool. Masses were subsequently celebrated at two locations, (probably private homes), in Irishtown.
In 1853, responsibility for Irishtown was transferred to the new parish of Petersham, but in 1858, responsibility was returned once more to Liverpool.
From approximately 1885, Irishtown passed into the care of the newly created parish of Rookwood, (Lidcombe), and was to remain so until St Felix’s became a parish in its own right on the 17th March, 1916.
Particular milestones in the history of the parish include the following:
