The Julias, Thomas (Tom), maybe even Antonias and Imogens circa 1970 were comparatively few and far between. The children with these names seemed to grow into them and the names just got better with age. You can probably think of better examples.
There were other much more popular names, Steven, Jackie, Claire, Alison, Lorraine, Julie, Sharon, Karen, Kevin etc. Sarah, although a classic, was also going through a popularity surge back then, ditto Emma. Perhaps some haven worn as well?
So who can pick a 'Julia', 'Thomas', 'Imogen' etc of 2010? It has to be the sort of name where for 10 years or so they will likely be the only child of that name in the class and the next generation will pick up on the name and use more broadly.
A name we've all heard of but not quite in vogue as yet. The sort of name that is a grower.
I'll have a try:
Daphne
Judith
Gloria
Natalie
Jaqueline
Caroline
Gillian (?)
