Yes. Loughmore and Loughmoe are one and the same place. Loughmoe is the older version of the placename, coming from the Irish (Gaelic) Luach Magh. Magh means a plain. Lough does not, in this instance, refer to a lake. There is no lake in Loughmore, just the river Suir......
I came upon this site a bit too late to join in this discussion, however I agree with bijou.
I have relatives in the village and have spent many happy times there.
I was last there in June '07 and will be back there in '09.
There has always been confusion about the old and new spelling, except among the local people.
I find it amusing as it often allows the locals to remain undisturbed.
It has always been a hard-working agricultural village, not a tourist place at all.
The Purcell or Loughmoe Castle, (I have seen both names used) where I played with my cousins as a child, is on private land. There is one Church (R.C.) one school, one pub, one small shop. Nowhere to stay, unless you want to improve your fiddle playing at Fiddler's Retreat.
I have a DVD made from a video all about life in Loughmore and Castleiney. It was filmed by a local about 15 years ago, and has a young lady telling the story of the Loughmore/ Luach Mhagh name. She then sings a sean-nos song about the Cormack Brothers, 2 local brothers wrongfully executed in 1858, who are now buried in Loughmore Churchyard.
If there is still any doubt about the name, please read this:
