Eimhín · Co. Limerick
Yes, that is the name. It is named after a saint, and the locals had to fight Facebook to prove it.
Effin is a townland and parish in south Limerick, sitting on the R515 midway between Kilmallock and Charleville, with a parish population of around a thousand spread thinly across farmland. The name is the thing everyone knows it for, and it is not a joke at the village's expense. Effin is the anglicisation of Eimhín, after Saint Eimhin, who tradition holds founded the first church here before moving on to Kildare and giving his name to Monasterevin. The Irish is pronounced EF-in. The English spelling simply landed where it landed.
There is genuine charm in the accident. The first written record, from 1240, calls the place Effyng. By 1287 it was a prebend of the Church of Limerick - a clerical living attached to the cathedral - and one of the men who later held that prebend was Edmund Spenser, the Elizabethan poet who wrote The Faerie Queene while planted on confiscated Munster land. He is unlikely to have spent much time in the parish. The living was a salary, not a home.
The village proper is small: the church that Father David Nagle built in 1835 to 1836, a GAA ground, a scatter of houses, and Davy's Bar. The parish around it is dairy country, the Golden Vale, the kind of intensively farmed land that does not photograph but does feed the country. The Ballyhoura Mountains rise at the southern edge, the border with Cork. Around thirty ringforts survive on the maps, the fortified farmsteads of families who lived here before the 12th century.
In 2011 Effin had its fifteen minutes. Facebook blocked residents from listing it as their home town, having decided the name was offensive. A local campaign, a deal of press, and a good deal of laughter later, the company relented by Christmas. The Effin GAA jersey and the parish road sign have been quietly popular souvenirs ever since. If you stop here, you will have stopped in a place so quiet you will hear the wind, in a parish that had to argue with a tech giant to be allowed to exist under its own name.
