I’m a [name_f]Jennifer[/name_f] from the mid-70s, so I grew up with at least–at LEAST–one other [name_f]Jennifer[/name_f] in all of my classes. When I was a kid, it didn’t bother me. I bonded with some Jennifers over sharing a name. Somehow, being a [name_f]Jennifer[/name_f] was different from being anything else.
As a teen, it exasperated me a little to have such a common name, but really, what doesn’t exasperate teenagers?
I’ve mentioned on this site that I think [name_f]Jennifer[/name_f] would be a perfect NB name, too, if not for its rampant overuse for thirty years. It’s an interesting combination of sounds, and unlike some names, there aren’t really infinite variations of it, either (as mentioned by pp toronto87 re: [name_f]Christina[/name_f]/[name_u]Christie[/name_u]/et. al). It also has an interesting evolution and history: Gwenhwyvar, [name_f]Guinevere[/name_f], [name_f]Jennifer[/name_f]…it’s ancient, which is really cool.
So now, as an adult, I have to say I love my name and I even feel that it’s a bit unique despite it’s popularity. It doesn’t sound cute or trendy or even dated (in the way names like [name_m]Keith[/name_m] and [name_u]Sandy[/name_u] are) even though there are so many of us. The Hollywood Jennifers ([name_u]Lawrence[/name_u], Lopez, [name_u]Connelly[/name_u], [name_m]Jason[/name_m] [name_u]Leigh[/name_u], Aniston, [name_m]Garner[/name_m], [name_m]Morrison[/name_m], and Goodwin–because she counts, even with a Gi-, b/c she was born a Je-) are all pretty cool and unique in their own right, too.
I do not know that I would use a super-popular name, though, especially one without a lot of the qualities I like in my own name, like sound, longevity, or commonalities of the type of name in general; i.e., I like [name_u]Aiden[/name_u] and [name_f]Caitlin[/name_f], but…there are just so many of them, and so many variations of them, and so many spellings of them…it’s overkill.
You don’t just have a lot of Aidens and Caitlins. You have [name_u]Aden[/name_u], [name_u]Ayden[/name_u], [name_u]Aiden[/name_u], [name_u]Aidyn[/name_u], Aeden, Aedyn, [name_u]Jaden[/name_u], [name_u]Jaiden[/name_u], [name_u]Hayden[/name_u], [name_u]Kayden[/name_u], [name_f]Caitlin[/name_f], [name_f]Catelyn[/name_f], [name_f]Kaitlen[/name_f], [name_f]Kaitlyn[/name_f], [name_f]Katelyn[/name_f], [name_f]Katelynn[/name_f], [name_f]Kaytlin[/name_f], [name_f]Katlin[/name_f], [name_f]Callie[/name_f], [name_f]Kaylie[/name_f], [name_f]Kaylee[/name_f], [name_f]Kayla[/name_f], [name_f]Katie[/name_f], [name_u]Kelly[/name_u], [name_u]Kelsey[/name_u], [name_f]Calla[/name_f], etc.
So if I were going to go with a popular name, I would go with something that stood out as a name, even if there are lots of babies with that name.
