Frisk: Believe it or not, this chunk of a dog was once very active when he was young. He was "Frisky" =D
Donovan: Named after the singer, of course! Also partially named after Don Lafontaine. Ah, two great people.
Indie: Hehe, no, her name isn't a shortened form of Indian(she is an Indian Ringneck). Instead, its derived from music she likes. On the ride home from her breeder(4-5 hour ride) we played a cd of a local indie artist at some point. Thats the first time she really began to chirp along with the music. She has good taste.
Lilly: Already named when we adopted her. I'm assuming lilies are white, or atleast can be white, and thats possibly how she got her name.
Gir: Originally named Ariel. Yeeeeh, it didn't go over too well with the family and she didn't even answer to it. On the car ride home(a 2-3 hour drive) my sister said that she would always chirp along with the doom song from Invader Zim. Needless to say, she was named after Gir from that show. :]

Khaith, Venny, Ophelia, Garber, Pocky, Mason, Akio, Greggory, Larry, Jill, etc.: were either named before we recieved them or they don't have a meaning behing them.
