The name of the young hero of Rudyard Kipling's The Jungle Book, who was raised by wolves (really) and becomes a genius hunter and trapper, was chosen as a middle name for their son Bronx (really, again) by rockers Ashlee Simpson and Pete Wentz. Kipling invented the name, whose first syllable rhymes with cow.

Fifi is a perfect name -- for a French poodle. But Fifi may seem more child-friendly as names like Coco and Lulu rise. Fifi in its fluffiness also balances the seriousness of such full names as Josephine or Federica.

Gert is an old school nickname for one of the oldest school names, Gertrude. Only the most adventurous, so-far-out-it's-in baby namers will choose Gertrude or Gert today, but it's definitely geek chic.

Marny is a spirited feminine name with diverse potential origins. It may function as a diminutive of Marna (Norse for 'of the sea') or Marina, or derive from the Welsh name Mairwen, meaning 'blessed Mary.' Some sources connect it to Marnie, possibly a Scottish pet form of Marina or Margaret. The name has maintained a consistent under-the-radar presence, never reaching mainstream popularity but appreciated for its friendly, approachable quality. Marny balances uniqueness with intuitive spelling and pronunciation, making it accessible without being common. The name carries a cheerful, youthful energy while remaining versatile enough for all ages. Its brevity eliminates the need for nicknames, offering simplicity in an era of more elaborate naming trends. Marny appeals to parents seeking something distinctive yet unpretentious.

Muffin originated as an English word for a small, dome-shaped baked good before transitioning into use as a pet name or term of endearment, particularly in British and American culture. As a female given name, Muffin is extremely uncommon and unconventional, typically functioning as a nickname rather than a formal name. It evokes qualities of sweetness, comfort, and a cheerful, unpretentious nature. The name carries a distinctly informal, playful quality that might appeal to parents seeking something whimsical and unexpected. Muffin's association with warmth and home-baked goodness gives it positive connotations despite its unconventional status as a human name. While rarely used officially, it occasionally appears as a nickname for names containing 'M' sounds like Margaret, Martha, or Meredith.
