<huge snip> Speaking of Dolohov, is that a true Russian name, anybody?
Or is the meaning of Antonin Dolohov a dead end, as Igor Karkaroff
appears to be? <snip>

Carol again:
To answer part of my own post, I looked up Antonin, which turns out to
be Latin(!) for "beyond praise." Now what exactly does that mean? So
praiseworthy that no praise is good enough (rather like that strange
word, "invaluable," which sounds as if it means worthless but means
"beyond appraisable value")? Or is it more like "beyond redemption,"
meaning "can't be redeemed"? If it's the former, and I think it is,
it's an ironic name indeed for Dolohov!

As for the surname Dolohov, all I could discover is that it's an
actual Russian name. Is it translatable?
