A common name in my husband's family is Xenophon. It's Greek. I pronounce it like Zeen-o-phone. He pronounces it like Ex-zan-o-fon. He loves to tell the story of his grandmother telling everyone, "No more Xenophon!" Apparently all the men up to that point had this same name, and she had had enough. I kind of wish we had given our baby this unusual name. We could call him X for short.
Xenophon is also the name of a Greek historian I would never have heard of if my husband hadn't told me the story of his family name. He has a Wikipedia entry if you are interested.
(I find it strange that the spell check recognized "Xenophon" but not "Wikipedia.")
