I did not see any apple tree as we passed the edge of HundredAcres but was intrigued somewhat as to the name.
We were speaking with JH from the area who had been told the story that there was a local land agent called Duncan who possibly worked for the same landlord as Captain Boycott. Captain Boycott worked for the 3rd Earl Erne, who would have held the title when the name came into use in 1827.
Duncan was asked by his employer to put together a parcel of land. He gathered 350 acres near Kilmaine and this was then gifted to him by the landlord. Upon his death, Duncan left 150 acres to his son and 100 acres to each of his daughters, which is what is locally believed to have led to the name of the area.
Subsequently, the son and one daughter moved away and the one remaining daughter purchased the lands to put the 350 acres back together again. Another visit will be required to try to establish more information and when, and why, the original Rocky Outcrop of the Apple Tree was re-introduced in the Irish version.
