Translation according to P. W. Joyce:
Ballyskeagh in Down, Galway, and Tyrone; Baile-sceach, the townland of the skaghs or thorn bushes. For Sceach, see [reproduced below] vol. i. p. 518.
The white-thorn or haw-tree - Irish, sceach [skagh]. From these thorn-bushes, so plentifully diffused over the whole country, a vast number of places have received their names. There are numberous townlands called Skagh, Skea, and Skeagh, i.e. simply a thorn-bush; and these, along with the shorter from, Ske, begin the names of many others such as Skeaganore in Cork, the bush of the gold, and Skenarget in Tyrone, of the silver, both probably so called because the bushes marked the spots where the peasantry dresamed of, and dug for money.
