No book could take into account the ever-changing landscape of name popularity which is why you need a website… say, a delightfully tongue-in-cheek one like Nameberry. They’ll give you name meanings (which you might want to cross-reference) and variations, of course, but what’s especially fun is checking out the latest baby naming escapades from the rich and famous. There are also a variety of really engaging lists, like Boys’ Names Dads Like More Than Moms, and Antiques Ready For Restoration that just might inspire.
I dig it, and I say that as someone whose name appears on the Old-Lady Cool Names list. Hmph. -Mir
