@jellyquest It's not the worst name I've ever seen but it's definitely pretty strange. Might be an issue when the kid grows up, Seven is not a good name in terms of being taken seriously as an adult. Did your friend tell you why she chose this name ? If it doesn't even have a personal meaning...
@abeshea Some suggestions could be :
Kamrie and Cassie, Kamrie and Kenzie, Kamrie and Katie, Kamrie and Kasey, Kamrie and Kallie, Kamrie and Capri, Kamrie and Carlie
@armodaughterofgod I'd go with Nella, because I don't think anyone minds (or knows) the meaning :)
If you're still hesitant, some suggestions could be :
Nova, Nola, Nyla or Nera
