LOL, yeah I think the only letter less popular here is C (we spell the k sound with a k, btw).
I'm stinking that in
Ocean Amethyst,
Jordan,
Riley,
Autumn, Rourke, Hoby (I'm hoping it's a nickname, but for what? Hobart?),
Marley,
Silas and Oak sibset the kids might be half-siblings. Or maybe Mom named some and Dad some? Who knows, but they do seem horribly mismatched.
