Tehallan, Civil parish in Monaghan Municipal District, Ireland

Tehallan is a civil parish in Monaghan Municipal District that stretches across several townlands, including Aghabrick, Alkill, and Annacramph. These areas form a network of settled territories in County Monaghan with their own spatial boundaries and local structures.

Medieval records from the 14th century list Tehallan in the Papal Taxation documents, showing that established religious administrative functions existed in the region at that time. This early written mention proves that the area was recognized as an organized ecclesiastical administrative territory.

The name Tyholland comes from the Irish Tigh Thalainn, "Talainn's house"; the parish is also called Tehallan. A large Celtic Cross at Tyholland Parish Church commemorates the Rice family, long active in County Monaghan politics. James Blayney Rice was the Fenian "Head Centre" for north Monaghan, and O'Donovan Rossa visited the Rice household here.

Those seeking historical information about the area can find resources like Logainm.ie and the Placenames Database of Ireland, as well as census records from the early 20th century. These sources are especially helpful for anyone interested in learning about local history and administrative structure.

Tyholland was the only part of County Monaghan active in the Fenian Rising of 1867: James Blayney Rice served as "Head Centre" for north Monaghan, and his grandfather had taken part in the 1798 Killyneill ambush. A large Celtic Cross at Tyholland Parish Church commemorates the Rice family's political work.
