There's a boy in my Cub pack who has a name which sounds like a very common boy's name but which has what I assume is a traditional Gaelic spelling. As a result it is more than twice as long as the more common spelling and has only the first letter in common. There is no possible way that anyone not familiar with the name could get even close to pronouncing it correctly. And it's not one I've ever come across before, such as Niamh, which is also tricksy, but slightly better known.
I just think that as a child life has enough challenges without being lumbered with a name which almost everybody is going to pronounce or spell completely incorrectly just to satisfy the parents cultural identity.
