I think that children of celebrities should attend school together. Hazel, Phinnaeus, and Apple might wind up having the most normal names. I like Phinn/Finn as a nickname.
Anyway, I don't think that those names are too bad. I have known people with unusual names: Tinkerbell, Cinnamon, Tashaka, Octavia. I was also surrounded by a multitude of Jennifers, Stephanies, Amys, and Lisas. I'm not sure which is better, to give a unique name or an extremely popular name. Plus my name is unique and unusual and I like it.
