I think
Harry Potter is definitely going to be the first thing that pops into people's minds in the US, where I am (at least if they have a very basic knowledge of the books or movies). For a while at least I think it's going to be firmly connected to that story, so it'd be inevitable to have them linked for a while.
However, will
Harry Potter be as pop-culturally relevant ten years from now as it is today? I don't know. I can't say whether the excitement over it will fade once the books stop coming out and the movies are all finished. In ten years,
Hermione might make a great name. I think it's unusual and pretty myself (it's growing on me, at least!). Maybe a kid named
Hermione today would bring to mind
Harry Potter, but once they're ten or twenty years old it might just seem unusual and very cool.
And even if the books are popular, if they endure twenty years of popularity after their completion then I think it's an acceptable connection anyway. Naming according to today's fictional fashions bugs me, but finding some smart and enduring name that was lent its popularity from fiction at some point in the past is fine, IMO. I just prefer that there's a substantial source behind a name, if you're influence from fiction, than some flighty trend.
