St Johnston
Taughboyne is located West-South-West from Derry, on the road to Raphoe; containing, with the village and ancient disfranchised borough of St Johnston, 6335 inhabitants (in 1837). St. Baithen, son of Brendan, a disciple and kinsman of St Columba, and his successor in the abbey of Hy, founded Tegbaothin in Tyrconnell: he flourished towards the close of the sixth century. The parish, according to the Ordnance survey, comprises an area of 15,773 statute acres, including a large portion of bog: the land is chiefly arable, and of good quality. There are some extensive slate quarries, but the slates are small and of a coarse quality.
