Holly ranks just outside the British Top 30, 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.
(She also could get a further boost from Baby Holly, daughter of Walter and Skyler on Breaking Bad.)
Jolly Holly has always been favored for girls born around Christmas, evoking the symbolic shrub with dark green leaves and bright red berries.
A memorable fictional Holly is the enigmatic heroine of Truman Capote's Breakfast at Tiffany's, Holly Golightly (almost named Connie, and with the full name Holiday), played indelibly by Audrey Hepburn. A real life one is actress Holly Hunter. Holly Short is a fairy character in Eoin Colfer's Artemis Fowl novels. And in Galsworthy's The Forsyte Saga, Holly and Jolly are siblings.
