@Liv999 I can’t comment on @Mooshamoo‘s views nor their history of posting on “Irish” threads as I am mainly posting on family related threads.
But I will say I think people need to be less prescriptive about what it means to be “Irish” - not all Irish people are catholic, Irish speaking, Gaelic and Bodhran playing stereotypes.
Not all have access to or want to learn Irish language, nor use Irish names, there will be local variation in names used and in the level of participation with Irish cultural activities and in the definition of what this comprises as culture varies across the island.
You have 6 northern counties and a further 5 that border the north where the name Saoirse - due to the politics - is going to be contentious. Several people have attested to that on here and I can assure you that the issue with Saoirse in Donegal did happen because myself and my husband were busy checking she was ok and that she got some safe after.
As a person born in the north, genuinely, despite having some catholic neighbours as a child I wasn’t aware of Irish names - all the catholic families we knew locally had gone for names like Robert, Samuel, Laura, Sarah and so on because they were middle to upper class and didn’t want their kids involved in any shit during the troubles. My experience of it, later as a teenager/adult, was that Irish names tended to be much more frequent, and indeed almost compulsory, in more working class communities where republican beliefs were held - and I know this because of the kids I met when I entered a mixed secondary school.
Now a few decades post cease fire the names are being used more broadly, even by Protestants, but Saoirse appears still to be contentious unfortunately. Which is a shame as I really loved it.
With regard to Cliona… I did meet one as a teen and realised it was Clion-ah… millions of Ciaran and Ciara’s, Conor, Aoife and Nuala’s.
But never came across names like Iarlaith, Caoimhin, Cliodhna, Oisin, Eoghan etc until late 20s/30s. (despite having lived in ROI for some considerable time by that point - again the people I was mixing with didn’t really have Irish names, odd one here and there but nothing accented or difficult to pronounce).
So I think to say that people from Ireland should know all Irish names and their pronunciation is a bit naive really. And to say someone is not Irish enough because they don’t know a name…. is to be too limiting in your view of what being Irish is.
