Rosehill is a townland in the civil parish of Templeport, County Cavan, Ireland.

[3] In medieval times the McGovern barony of Tullyhaw was divided into economic taxation areas called ballibetoes, from the Irish Baile Biataigh (Anglicized as 'Ballybetagh'), meaning 'A Provisioner's Town or Settlement'.

The original purpose was to enable the farmer, who controlled the baile, to provide hospitality for those who needed it, such as poor people and travellers.

The historical spellings of the ballybetagh are Ballymackgawran & Ballimacgawran (Irish = Baile Mhic Shamhráin = McGovern's Town).

[12] Affidavits by Francis Finlay and John Roycroft of Rosehill from 1825 show the church tithes of Templeport parish.
