@SomeHorse , I'm one of those.
The Irish names when I was at school were Kevin, Kieran, Kelly, Sean, Siobhan and Niamh.
You'd hear them get called Seen, Sigh-o-ban and Nee-um. Kieran got misspelt.
Nowadays, people will be familiar with them, but there will still be spelling mistake (including missing fadas).
@Helenalove , Everyone knows about the troubles in the past between the UK and Ireland. That's a sweeping generalisation. Some people know. Many won't.
tacky to use the names in the UK. - I think this, but I'd say it about most names from other cultures or languages.
The names that get used are often dated in the original culture, or they are mispronounced or misspelt, or they are faddy. (Caitlin, Ryan, Liam, Kelly, Kieran, Kevin). They are probably fine in Ireland.
The Irish association isn't normally one Irish parent and one British parent. It's usually a grandparent (if my age) or great-grandparent.
I have 2 sets of friends who are one Irish parent/one english parent. None of the children have Irish names.
