I love Dylan - it was on my list. I prefer the way it's usually pronounced in England and the US (dill-un), however, it's a Welsh name and I believe the correct pronunciation is actually more like dul-an, which I'm not as keen on.
Lewis - another one on my list, but DH not so keen. I like Lewi as a nn.
Charlie - nice, but more of a nn and a bit too popular for me.
Fraser - lovely, also on my list
Caspar - not keen, reminds me of ghosts
Cameron - I like it, love Cam as a nickname, but I could never use it as it reminds me too much of David Cameron!
I also like Miles, Niall, Ioan, Rowan Euan / Ewan, Wilfred, Auden, Orson, Joel, Jared, Ray and Rafe
