@User1990232, I would say it about any name.
I can't think of any Nigerian names off the top of my head, the Nigerians I know have names that are English.
The example names I gave in my last post are welsh. If you know how to say them, or if you heard them would know how to spell them, then fine.
Upthread there are examples of names not spelt correctly. Nulua was one of them and I think it was meant to be Nuala. I used to work with someone whose DD was a Nuala pronounced Noo-ahla. I know someone with a daughter called Naimh pronounced Neev.
These people have degrees and good jobs. They are not stupid, but they didn't research the names, did they.
Did you see the disagreement on this thread about how to say currently popular names?
People may or may not be stupid but if a name has a spelling that is not obvious, they may not know how to say/spell it.
It applies to English names too - something like St John Featherstonehaugh might be a pain, but so might Katherine Thompson.
If I point out that Ciara might get called See-ahra or Clara or have her name spelt Kira, Kiera or Keira, and that Cara might be easier, it isn't because I have something against Irish names, it's because I see the pitfalls.
