That is a good question! :D

Generally, we usually make the closest assumption to what the spelling is, example: Nathair, that seems to be the way it's spelt, Nath-a-ir. However, the official spelling could be "Nathayeer", or something. But the best thing we can do is make the closest assumption! :)
