Conall! It sounds good, reminds me of
Conor but more elegant (the end of
Conor can sound like a very undignified "errr" in an American accent) and it has a great meaning.
I don't like
Miles. It sounds very pedestrian and unimaginative to me, and also a little slimy or sleazy.
I love
Lyra. I like
Isla too, but it seems more popular and I honestly like how
Isla looks better than how it sounds.
