Charles Magauran, the Third, (Gaelic- Cathal Mág Samhradháin) was chief of the McGovern Clan and Baron or Lord of Tullyhaw barony, County Cavan including the period 1641 to 1657.
His ancestry was Charles son of Brian Magauran son of Feidhlimidh Mág Samhradháin (d. 1622) son of Brian son of Tomás (d. 1532) son of Maghnus (d. 1497) son of Tomás Óg (d. 1494) son of Tomás na Feasoige (d. 1458) son of Fearghal (d. 1393) son of Tomás (d. 1343) son of Brian ‘Breaghach’ Mág Samhradháin (d. 1298). His father Brian Magauran was his predecessor as chief of the clan. Cathal was the eldest son and his younger brothers were Domhnall (anglicised Daniel) Magauran and Feidhlimidh (anglicised Phelim) Magauran.
On the death of the McGovern chief, his father Brian Magauran, Charles took the chieftaincy and lived in Ballymagauran Castle.
Charles joined the Irish Rebellion of 1641 against British rule and he led the McGovern forces in the wars that followed.
The surviving British settlers later made depositions about the rebels activities, some of which mentioned Charles and the other McGoverns.
William Reynolds of Lisnaore made a deposition about the rebellion in Lissanover as follows:
