Tullyhaw (, which means 'the Territory of Eochaidh', an ancestor of the McGoverns, who lived ) is a Barony in County Cavan in Ireland. The area has been in constant occupation since pre-4000 BC. Located in the northwest of the county, it has been referred to as Cavan's panhandle. Tullyhaw was originally a túath within West Bréifne. It was later absorbed into East Bréifne in the sixteenth century. Glangevlin.com: History - The Kingdom Of The McGoverns. https://www.glangevlin.com/2021/05/13/the-kingdom-of-the-mcgoverns/
In 1579, East Bréifne, then part of Connacht, was made a shire. The shire was named County Cavan, being named after Cavan (), the area's main town. The administration remained in the control of the local Irish dynasty and subject to the Brehon and Canon Law.
In 1584, Sir John Perrot formed the shire into a county in Ulster. It was subdivided into seven baronies: two of which were assigned to Sir John O'Reilly and three to other members of the family; two remaining, possessed by the septs of McKiernan Clan and Mac Shamhráin (McGovern or Magauran) The last one, Tullyhaw, encompassed the mountains bordering on O'Rourke's country, and was left subject to the ancient tenures and exactions of their Irish lord.
