Newbie/ Karkaroff's name

[A B]

No: HPFGUIDX 11175

Hello. I'm relatively new to Harry Potter, having just
recently read the series, but I really enjoyed it (in
fact I read it all again once I'd finished GoF). I
also consider myself a fairly serious Tolkien fan.
When I read GoF Karkaroff's name struck me as being
very similar to Carcharoth (the "ch" is a gutteral
sound as in German, not the English sound), an evil
wolf in the Silmarillion. For those unfamiliar with
Silm., Carcharoth is sent by the original Dark Lord to
guard his gates from a great hound, he bites off the
hand of one of the heroes and eventually causes this
heros' death. Does anyone think there could be
possible parallels drawn with Igor Karkaroff?
