What do you think of
Taliesin? With the middle name
Dylan and the surname Evans? I really like it as it's got a lot of history behind it and a lovely meaning. I think Tally would make a cute nickname for a little boy too. ^^ Pronounced tal-ee-ES-in or tally-ESIN (those are the pronounciations I hear most often) by the way as I know that's going to be an issue.
