History of the Monaghan name

Monaghan is Ó Manacháin, from manachán, a diminutive of manach, 'monk', and has no connection with the county of Monaghan, whose name means 'place of little thickets'. The sept were chiefs of a territory in north Roscommon near the Shannon, recorded in the annals from the eleventh century, and Roscommon together with neighbouring east Mayo and Galway remains the name's heartland. A separate concentration grew up in Fermanagh. The spelling Monahan is common in America, where the name has prospered in film and letters.
