I love Cliona, tested it on DH, he pronounced it wrong, but quickly picked up the correct pronounciation once corrected
I thought about changing the spelling, but is that a bit tacky? and IMO Cleona would be pronounced like Leona (very long O sound, wheras the O in Cliona is shorter) which I don't like
I used to have an Irish surname and it was a PAIN in the UK, however it was the type of Irish name which people still didn't get/pronounce/spell even when corrected IYKWIM, is Cliona an easier one to get, I can see it would need to be corrected once but its not that hard is it?
