Jolly Holly has always been among the favorite names for Christmas babies, evoking the symbolic shrub with dark green leaves and bright red berries. And Holly is the flower for the month of December, so it's also among the perfect names for December babies. Holly is scarcely heard on baby boys, but Robin Tunney and Nicky Marmet used it as the middle name for their son Oscar.

Holly ranks just in British Top 50, but it's been out of favor here since the 1970s Era of Nickname Names. Still, the name may be on her way back as a rejuvenated nature pick.
