Some of the recent posts have introduced me to the concept of double barrel names which I hadn’t thought of before. Problem is, most of them sound a little too Southern for our tastes. [name]How[/name] about some solid double barrel Gaelic names?

I hope these help! I stuck mainly to Irish names as this is what you seemed interested in in your previous posts but I do have a lot of knowledge of Welsh names (live there and speak the lingo) if you’re interested in other Celtic names 
A really popular one is [name]Aine[/name]-[name]Maire[/name] (pn An-ya Mah-ra)
