In Dungeagan (see my previous question) there is an Arts Centre called Cill Rialaig. Could anyone provide me with more information about the word Rialaig (is it a noun, a name (meaning?))?

Thanks again.

It is Cill Rialaigh or in older spelling Cill Rialaiġ (i.e. a ġ with a dot).
In the dialect Rialaigh is pronounced Rialaig, i.e. with a g´-sound at the end, so perhaps even so written.

Rialaigh is the genitive form of Rialach, probably a name but truncated.
Older forms are Oirbhealach, Iorathaluch, Irgalach etc.
