An Irish one which always used to catch me out was Maynooth, pronounced Muh-nooth.
In my experience, pronunciation of Irish proper names can be fraught with surprises and errors for English folk such as myself (and presumably for Scots, among them yourself, hexagon789 ).
Older participants like me, are apt to have been in the position of first encountering place names in Ireland, in articles in the railway press about railways on that island -- reading the names, but; if like me, with effectively no family Ireland-related links; never having, then, heard them spoken. (Re Ireland's more northerly parts -- said reading happened in times before circumstances arose, in which Northern Ireland and places therein came to feature with great frequency on radio and TV news.)
An example: as a kid some sixty years ago, reading about the big junction, meeting-point of the broad-gauge Great Northern Railway of Ireland and the 3-ft.-gauge County Donegal system -- I naturally enough mentally transliterated, so as to pronounce its name as "Stra-BAYN". Discovered much later, that it's Stra-BAN. The same has gone for me, for a good many Irish places, both in the North and the Republic.
One in N.I. which continues to perplex me a little, is Omagh. I've heard it pronounced by apparently equally authoritative sources, as "Oh-MA[C]H"; and "OH-mah". Can anyone knowledgeable re this issue, provide enlightenment?
