Ok, you don't need to freak out on everybody. You asked for opinions on a name, and unfortunately people's cultures and cultural predispositions affect how they see a name. We live in a very international society, and having foreign perspectives on a name is something you should be grateful for, not angry about. The fact that your pronunciation doesn't work in the US could mean
Elin would face difficulty if she were ever to travel here, or move here, or interact with people from here.
So, my opinion on the AY-lin pronunciation: You either sound like you're saying "Hey,
Lynn!" and trying to get
Lynn's attention or it sounds like "ailing" like you have an ailment. I also feel the fact that
Elin's English and Welsh relatives would pronounce her name differently to be something to avoid, perhaps it would be a name better left for the middle-name slot.
