Don't want to stress you out too much - but are they pronounced pretty much as they're spelt because as a teacher (and I used to do relief so would have to go off the written class list on names) it can be quite tricky to work out how to pronounce names. I still have trouble with a couple of names (Kirsty and Kristy as they're very similar and I had one of each in my class at one point are just one example). But if you really like an unusual name don't let that stop you.
