History

The civil parish of Desertmartin derives its name from the ecclesiastical parish, which in turn is named after an ancient church allegedly built as a retreat by St. Columba in the 6th century in honour of St. Martin. This gave its name in Irish; Díseart Mhartain, the hermitage of St. Martin. It is also recorded however that it was built by St. Martin instead.

Loughinsholin

At some stage a crannog (an artificial island) was built in the only lough within the parish, lying in the townlands of Anagh and Stranagard. This lake would be later called Loughinsholin , and the name is preserved to this day as the name of the barony of Loughinsholin.
