Tournafulla-Mountcollins parish was formed in 1838 from part of the parish of
Killeedy. Until 1586, Mountcollins had been part of the parish of
Monagea. The present-day population of the parish is about 1,500 people. Mountcollins was formerly called Knockroedermot. The area used to be called the "Munster Coalfield". A large tract of land was reclaimed here in the middle of the nineteenth century. There are hills to the north and southeast, and the land is mainly boggy. In the past, there was little more than a road in Mountcollins and people used to say, "I'm going to the road" in reference to it. During the famine in Mountcollins, a number of new roads were laid as part of the relief works that began nationwide in an effort to alleviate the immense poverty that existed at the time. Mountcollins got its present name from Fr. Luke Collins. Fr. Collins served as priest to both Abbeyfeale and Mountcollins from the 1730s until his death in 1775. Fr Collins first said mass in a building on a hill called 'the Mount', which is the site of the present-day church. Hence the name Mountcollins. The
Ó Coileáin ruled Southwest Limerick from the fourth to the thirteenth century. The area was called the Tuath of
Corca Oíche, after the clan. The Gaelic lords of the Corca Oíche took the name Ó Macasa which became anglicised as Mackessy. To the east of Corca Oíche lay the lands of the Ó Coileáin called Claonghlais. The name Ó Coileáin was anglicised as Collins. == Employment ==
