What the name remembers
The flagstone church
Cill na Leice translates as "church of the flagstone" — a cill being an early Irish church or monastic cell, leice being a flat stone or flagstone. The specific stone is not recorded and probably not surviving. What it suggests is a church built on or beside a stone that was significant enough to name the whole settlement after — possibly a monastic threshold stone, possibly a boundary marker, possibly the slab over an important burial. The practice of naming early churches after their physical features or their founders is common across Ireland; in Kilnaleck, the feature was the stone, and the name has held for over a thousand years.
1879, and then nothing
The coalmine
In 1879 a local schoolmaster and a group of Kilnaleck businessmen secured backing to sink a coal shaft near the village. The geology of south Cavan had suggested something was there, and they were right — the seam existed. The problem was extraction. The coal sat too deep to bring up at a price that made commercial sense, and the venture wound down before it produced anything of scale. The shaft was filled, the investors moved on, and Kilnaleck remained a farming village rather than becoming a mining town. In a county where the land had a way of promising things and then not delivering, the 1879 coalmine fitted the pattern.
From Crosserlough to the Chicago White Sox
The Comiskey line
John Comiskey was born in the parish of Crosserlough in 1826 and left Ireland during the Famine, making his way to New Haven and then west to Chicago. He built a career in politics — alderman for multiple wards, eventually Clerk of the Cook County Board — and he raised a son, Charles Albert Comiskey, who became one of the central figures of early American baseball. Charles Comiskey was a first baseman, a manager, and then an owner — he co-founded the American League and owned the Chicago White Sox from 1900 until his death in 1931. The club still plays. The man who set the family on that trajectory was born in the civil parish that includes Kilnaleck, in 1826, and left because the land could not hold him.
Lehery townland
The Penal Laws mass rock
In the Lehery townland, within the Crosserlough parish, there is a mass rock — a flat outdoor stone used for celebrating Catholic Mass during the Penal Law period, when Catholic worship was banned or severely restricted under British law. Priests celebrated Mass in the open air, often in remote locations with lookouts posted for soldiers or informers. The mass rocks that survive are among the more direct physical records of that period in rural Ireland. The Lehery stone is not a monument or a heritage site. It is a field stone that people used when using a church was dangerous.
The GAA club, 1966–1972
Crosserlough seven in a row
Crosserlough GFC, based in Kilnaleck, won seven consecutive Cavan Senior Football Championship titles between 1966 and 1972. Seven in a row in county football is not something many clubs have done anywhere in Ireland. The achievement belongs to a club from a small south Cavan village and is, locally, known without needing to be explained. The Crosserlough ladies team won the Cavan Senior Ladies' Football Championship in 2021, adding to a club record that has lasted sixty years.
