I'm really sorry to say it, but they will date to this era. It's not only the Jayden, Neveah types names that date, but also the very popular, typical-of-their-time names. And ie/ee/y ending names are very much of this era. Charlie, Harry, Alfie, Billy, Archie, Lily, Millie, Lily, Tilly, Evie, etc, etc, ad nauseum.
Names like Joanne, Karen, Claire, etc are not bad names at all, but they definitely date to their era.
They're not to my taste - to me they sound dated already. But - who cares? If you like them, that's the main thing. :)
In the interests of full disclosure - my DS has an 'y' ending nickname, but his full, BC name doesn't end in this sound. Plus, his name is on the retro baby name thread on the go at the moment, so he's really the only with his name around at the mo.
