Drumbeagh (from Irish: Droim Beitheach meaning The Hillridge of the Birches) is a townland in the civil parish of Templeport, County Cavan, Ireland. It lies in the Roman Catholic parish of Corlough and barony of Tullyhaw.
Drumbeagh is bounded on the north by Gubrawully townland, on the west by Altinure, Tullandreen, Tullynamoltra and Corraclassy townlands and on the east by Curraghabweehan, Derryvahan and Drumcar (Kinawley) townlands. Its chief geographical features are the Owensallagh river (A source of the River Blackwater, County Cavan), forestry plantations, a stream and dug wells. Drumbeagh is traversed by the R200 road (Ireland) and rural lanes. The townland covers 187 statute acres.
In the Plantation of Ulster by grant dated 27 February 1610, along with other lands, King James VI and I granted one poll of Drombeagh and Corroboan to William O'Shereden, gentleman, Cheefe of his Name. William Sheridan was the chief of the Sheridan Clan in County Cavan. He was the son of the previous chief, Hugh Duff O'Sheridan of Togher townland, Kilmore parish, County Cavan. William was the ancestor of the famous Sheridan theatrical family. William died sometime before 1638 leaving two sons, Owen (of Mullaghmore, Tullyhunco) and Patrick (of Raleagh townland, Kildallan parish). Owen Sheridan succeeded to his father's lands. Owen's son Denis was born in 1612 and became a Catholic priest in charge of Kildrumferton parish, County Cavan. He later converted to Protestantism and on 10 June 1634 William Bedell, the Protestant Bishop of Kilmore, ordained him as a Minister of the Church of Ireland and two days later Denis was collated to the Vicarage of Killasser in the Diocese of Kilmore. Denis had several children, including William Sheridan (Bishop of Kilmore and Ardagh) 1682-1691 (his son Donald kept up the Templeport connection by marrying Mrs Enery of Bawnboy); Patrick Sheridan, Cloyne, Protestant Bishop of Cloyne (1679-1682) and Sir Thomas Sheridan (politician) Chief Secretary of State for Ireland (1687-1688).
