Shame about that, Kieran Doyle is a great name, and Kieran has actually been my favourite male name since I was 10. It came close to being my name, but it doesn't quite suit me. I'd go for a longer middle name since Kyle is so short, of at least 2 syllables... Alexander, Anthony, William, maybe.
I wanted my middle name to be Sebastian (seh-BAst-ee-an) before I knew I wanted my first name to be Nikolai. It's an unusual combination, but in a strange way it fits me. Also, I was destined to have a strange name even if mom picked it... she was rooting for Aimhirghin Picasso at one point.... sigh. I also considered the addition of Alan because that was one of my top two choices for what I wanted to be called when I was younger, but I already have a hyphenated last name, so that seemed like overkill.
