That's my favorite poem, too! I understand your excitement. :D Kubla nn Kub made me laugh, the poor kid. As for your fantasy sibset:
Simon Xanadu- I love
Simon, and Xanadu, frighteningly enough, I am really beginning to like.
Rudolf Zimri- Not a
Rudolf fan, but it flows well with
Simon and
Lucius.
Zimri is excellent.
Lucius Valentine- Very cool!
Valentine on a boy, perfect. I like all three combos.
Xanadu as a posting name: That would be recognizeable, for sure. Go for it!
I'm stuck on non-name names from songs/poems/etcetera. I did get a lot of my favorite "real" names from those places, though.
Iris is from the GGD song, and I have half a dozen Tolkien names.
PS- Xanadu
was a place. Xanadu, aka Shangdu, was Kublai Khan's capital; it's in Mongolia somewhere. :)
