I have just returned from a week in Loughmoe (Loughmore). On last Tuesday, 2/17/09 I walked nearly the entire distance of the old road up from Thurles to Loughmoe. I was tracing the several local townlands of my own heritage. I am the first of the line to return since the famine departure. I hail from Hayes, Finigan, Ryan, and Maher. I now have firm paper record back to circa 1790 in these townlands. I met for hours with Monsignor Maurice Dooley of the local parish who gave me a wealth of history and church record.
Regarding the village name, as we walked north on the old road we found this sign:

As we reach near to Loughmoe Castle, we found this sign:

BTW, the local (only) pub recently changed names. It was Loughmore Inn for years, but is now Stapleton's bar. Exceptionally friendly people.
I have been unable to locate any date information about the old, stone Loughmoe Abbey in the cemetery of the current local church.
