I purposely avoided popular names - didn't take into account other countries too much, although the only relevant countries (we're in a different one now from where the DC were born) have more or less the same popular names.
There is a vast swathe of names in between the top 10-type, overly popular names which will inevitably date (and sometimes badly) to a particular era - and silly names such as Jux's examples.
I don't understand why people struggle to get this so much, to be honest.
I am glad that I don't have a Sarah/Claire/Joanne/Nicole/Karen/Angela/Andrea type name from my generation - nice names as they are and no offence intended, they are tired and dull now through overuse.
As I say, there's a zillion and one names in between massively popular and made-up, individual yoo'neeq names. It's not about trying to bestow a name on your child that no-one else will have; but about choosing a more timeless, less dateable name that isn't all over every playground and school classroom, and that won't, in another generation, be positively eschewed because it's so done.
Your name is your main, and by far most widely used, identifier - why add to the multitude of Rubys, Millies and Evies if you don't have to?
