They do to, gosh you guys maybe if you paid attention to what Chewie said you would know, he said it loud and clear in the movies over a dozen times. Brndon0125: His full name is Chewbacca Rahhggaahh Urughaghhh. I don't know how you guys missed that.
It's in both the Young Jedi Knights books when Lowbacca is first introduced I believe, and also in New Jedi Order at the funeral of Chewie on Kashyyk
Rwookrrorro Category: Locations Type: Cities Planet of Origin: Kashyyyk Chewbacca's home village on Kashyyyk, and one of the planet's most metropolitan centers of activity. It was a kilometer-wide platform built in a tangle of huge wroshyr trees. One huge branch had been hollowed out by the Wookiees for use as a hangar, and smugglers routinely evaded Imperial patrols to deliver supplies and weapons to the Wookiee underground. I don't think he has a last or clan name.
His first name is Chew and his last name is Bacca. It just sounds like one name because it sounds so natural. It's not like Han would say "Lets go Chew", instead it's Chewie or they say both his first and last name, "Chew" "Bacca". lol Just kidding, I don't know
