First of all, make up your mind, are they Scottish or Welsh? They're two completely different languages! You can't have both, it wouldn't make sense.
Secondly, Aluralynn is a made-up modern American name which no self-respecting Scottish king would touch with a ten-foot pole. I realise your director may have chosen that, but if you can you should get her to change it to something that's actually Scottish.
Now, on to the fun part! Here are some nice Scottish names you could use . . .
