Saw this humor item, though, and thought I'd add some thoughts:

Remember that Joan's maiden name is Macht. So would she be considered a Macht 1, and Roger a Macht 2?

On a more serious note, I wonder if there was any symbolism intended in her name. "Machen," if I remember any of the German I took over twenty years ago (yikes!!), means "to make." "Macht" would be a conjugation of that verb (er/sie/es macht ... he/she/it makes).
He usually chooses names because of their sound and/or inherent meaning. Can anyone think of what "Macht" may have been meant to convey? It might not make any differene in the Last Chronicles, since the name was chosen when there was only three books in his plans. But ... any ideas? Is there a less common connotation of the German use of the word that wouldn't be obvious to low-level students in the US?
