Some of these just seem like such common names that it's implausible to link them to one random celebrity with the same name. Others are more likely... since you have fictional characters on here I'm kind of surprised that Jacob, Edward, and Bella/Isabella aren't on here. But, like, for instance, I have a very hard time believing that there is anyone out there who named their child after Christopher Walken. Christopher Reeve? Sure. But not Walken.
The ones in the quiz aren't the only baby name booms due to celebrities, maybe Jacob and Bella also had a boom they just weren't in my sources. Have a read of my first source for their methodology on the Christophers.
