No, you've completely misunderstood, no offence
I'm trying to advise somebody who feels uncomfortable using the name Niamh! A name which is in the UK top 100 and from a directly neighbouring country which has many links with UK.
I would never judge anybody else who gave their child an African name or a Chinese name for example, but personally, by my own yardstick, that is where I would draw the line so to speak. Can I blend in to that culture/country or not?!
That seems like a logical place to decide, OK I'm comfortable with foreign names for my own child up to that point. We're all entitled to identify what feels natural, and at what point it wouldn't feel natural iyswim.
Irish, Italian, Greek, French names; that's all completely fine for me. Personally, I wouldn't have considered an African or a Chinese name no matter how pretty it sounded or how lovely the meaning. I would have felt self-conscious and faintly ridiculous about it.
We all have our own barometre of what feels natural and what doesn't feel natural. That's the point. I do understand where the OP is coming from, although I wouldn't limit my pool of names to the same extent.
btw My cousins were brought up in Zambia but they are called Caroline, Elizabeth and Stephen.
