Kind of, Jon. You can look up everyone with a given name and then figure out which of those servers are where (eastern time, etc).
Google the word "Armory" and, if nothings changed, it'll be the first link.
For instance my brother plays the character Elmdor. If you search the armory for Elmdor you'll see everyone with an active account who has a character names Elmdor so long as that character is level 10 or higher. Without knowing which server he is on it will be hard to figure out which character is actually his.
Any other details help of course, like what level the character is, his race, class, guild, ect.
In Cale's case its an Undead Warrior in The Dark Carnival on Eonar.
