The Tierneys  of Leinster

O’Tierney sept of Leinster are believed to be descended from Tighearnach, king of Breaga and Loch Gabhair. They are said to be descended from Niall Naoíghaillach or Niall of the Nine Hostages, as he is better known. So far little is known of this sept except that Breaga was a Kingdom whose boundaries extended from within the River Liffey in the South to the River Boyne in the north. It stretched from the outskirts of Dublin in the East to the River Shannon in the West. It is thought that it may at one stage have formed the Fifth ‘Cuige’, or the Fifth Province. It was from this province that the High Kings of Ireland ruled their Kingdoms. History tells us that Tighearnach lived in the great Crannog of Lagore [Loch Gabhair]. Lake Lagore {now dry due to a drainage and land reclamation scheme] was situated in Co. Meath in an area between the Villages of Dunshaughlin and Rathoath, about 30 Kms to the North West of Dublin. His crannog [or lake dwelling] was a large fortified dwelling built on the lake.  William Wilde, one of the earliest crannog researchers in Ireland made a visit to Lagore in1839 when local labourers whilst digging exposed “the royal crannog of the Early Medieval kings of Southern Breaga [Rhoda Kavanagh] , which is dated from the 7^th to the 10^th centuries. It is recorded that ‘exciting archaeological discoveries were made at this location'. Tighearnach was slain in battle in about 850 AD leading his troops against the Danes who he defeated on numerous occasions. In 846 he fought his most famous and best documented battle at Doire Dhisirt dhá Chonna or as it is also known Drom da Chon against the Lochlonnaigh [the Danes] where he inflicted a great defeat on them.
