Hmm. I don't like Cyril much, and that surprises me some. I like a number of similar names, like Cedric, Cyrus, and even Cecil. Cyril sounds a little wormy, for lack of a better term--sort of slippery and wriggly. I love Kira. It has a totally different vibe, though.
I adore Cecil. I'd suggest it more, but here in the U.S. the "SEES-l" pronunciaiton really bugs me. :-/I agere about Kira having a different vibe. It's interesting how two related names can do that. Thanks for the feedback. :-)
