"KILBIRNIE derived its name from the parish church and the church obtained its name from the saint to whom it was dedicated; the Celtic Cil, pronounced Kil, signifying a church, being prefixed to the name of the saint; St. Birinie, or Birinus, is said to have been a bishop and confessor who converted the West Saxons and died at Dorchester in 650 AD and was commemorated on the 3d of December.
In the vicinity of the church of Kilbirnie a village has arisen during late times. In 1740 there were only three houses here; but, by means of manufactures, it grew to be a village of 80 houses which were inhabited by about 300 people in 1791. In 1821 the village of Kilbirnie contained about 800 people."
