Billee Origin and Meaning

The name Billee is a girl's name.

Billee is an uncommon feminine name that originated as a playful, alternative spelling of Billie, which itself began as a diminutive of masculine names like William or feminine names like Wilhelmina. The distinctive double-e ending gives this variation a whimsical, creative quality. Popular primarily in the mid-20th century, Billee peaked between the 1930s and 1950s when nickname-style given names were fashionable. The name carries associations with liveliness and spunk, often connected to the tomboy aesthetic that was celebrated in that era. While rarely used in contemporary naming, Billee retains a vintage charm and informal sweetness that might appeal to parents seeking something unconventional with historical roots.
