Supernatural name theme, someone help?

I have 3 gerbils, 1 male and 2 female.. I don't really no anyone to ask this except other Supernatural người hâm mộ but I'm looking to interesting and creative names from the hiển thị for the 2 females. They don't have to be actual names like I named the male Colt, after the obvious. But I'm stuck on names for the girls. Alot of the names in Supernatural are pretty ordinary to say the least (Jo, Ellen, Pam, Jess, Mary...) so I'm stuck. I wanted something creative that made it where bạn really had to be a người hâm mộ to see the theme behind it. Anyone able to help out here?
