Matha Mág Tighearnán

Matha Mág Tighearnán (anglicised Matthew McKiernan) was chief of the McKiernan Clan and Baron or Lord of Tullyhunco barony, County Cavan from 1290 until 1311.[1]

Ancestry

Matha was the son of Gíolla Íosa 'Leith' Mág Tighearnán, son of Sithric ‘Carrach-in-Cairn’ Mág Tighearnán (d.1290), son of Duarcán Mág Tighearnán, the Second (d.1290), son of Íomhaor Mág Tighearnán, the Second (died c.1269), son of Tighearnán, son of Duarcán the First, son of Íomhaor the First, son of Gíolla Chríost, son of Amhlaoibh, son of Tighearnán, the founder of the clan.[2] His grandfather Sithric ‘Carrach-in-Cairn’ Mág Tighearnán had been a previous chief of the clan. Matha’s brothers were Domhnall ’An Saithnech’ Mág Tighearnán (d.1312) who succeeded him as chief of the clan, Conchobar ‘Buidhe’ Mág Tighearnán (d.1314) who was also a chief of the clan, Tomás Mág Tighearnán (d.1358) who was also a chief of the clan, Duarcán, Cú Chonnacht, Cormac, Fergal 'Cend Craiche' and Mathghamhain (d. 1314).

Chieftainship

On the death of the previous chief, his grandfather Sithric ‘Carrach-in-Cairn’ Mág Tighearnán in 1290, Matha took the chieftaincy and resided in the castle of Croaghan of the Cups (Irish- Cruachan O'Cúbhrán), now in the townland of Coolnashinny, besides the modern town of Killeshandra. The McKiernans were involved in a running feud with the neighbouring O'Reilly clan.

In 1301 there was a clash in the McKiernan lands with the O'Reilly and McGovern clans on New Year's Day. It happened in the townland of Aghnacor, parish of Killeshandra, barony of Tullyhunco, County Cavan, but the annals give different dates. Matthew O'Reilly was killed in the clash. He was the son of the Lord of East Breifne Gilla Isu Ruad mac Domnaill O'Raghallaigh (reigned 1293–1330), and son-in-law of the chief of the McGoverns, Brian ‘Breaghach’ Mág Samhradháin (reigned 1272-1294), being married to Brian's daughter Gormlaidh. Poem 9 in the Book of Magauran[3] [4] is dedicated to Mrs Gormlaidh O'Reilly-McGovern and was written at the time of Matthew O'Reilly's death by the poet Maol Pádraig Mac Naimhin (or Cnáimhín). Stanza 37 refers to Matthew's death as follows-
