Who comes after Otis Basil?

Albert has acquired a new gloss as one of the top royal baby boy names, a considerable upgrade from its serious, studious image (think Einstein, Schweitzer).

When actress Rachel Griffiths chose this highly unusual name for her son, many assumed it was a bizarre invention. But a noted Australian poet (Griffiths is an Aussie) is known by this name.

Clementine is a Nameberry favorite that broke back into the US Top 1000 in 2014 after more than half a century off the list.

Despite a return to such feminizations of male names as Josephine, Clementine, and Theodora, starchy Henrietta has not made it into that group. Still, if you look hard enough, you'll see that Henrietta has the same vintage charm.

Lottie is a nostalgic great-grandma name that conjures up lockets and lace, and — like Nellie, Josie, Hattie, Tillie, and Milly — has considerable vintage charm.

Posey is fashionable in England, a country of gardeners, but this pretty bouquet-of-flowers name is only starting to be heard here.

Rue has gone from Golden Girls actress to Hunger Games heroine. This botanical name is also a coincidental double word name, meaning "regret" in English and "street in" French. Despite these unfortunate secondary meanings, Rue has real potential to be one of the most popular new middle names for girls.

Rupert is a charming-yet-manly name long more popular in Britain (where it's attached to a beloved cartoon bear) than in the U.S. Yet we can see Rupert as a more stylish, modern way to honor an ancestral Robert.

This pet form of such names as Winifred and Edwina and Gwendolyn has loads of vintage charm, a la Millie and Maisie, with a decidedly winning vibe. And it just got celebrity cred as the baby daughter of Jimmy Fallon.
