What is the meaning of the name Billie-Joy ?

Billie-Joy is English in Origin.

Billie-Joy blends a jaunty nickname with a virtue word. Billie is the pet form of William or Wilhelmina, from the Old High German elements wil “will, desire” and helm “helmet, protection.” Joy descends from Middle English via Old French joie and ultimately Latin gaudium, meaning “delight, gladness.” Together, Billie-Joy suggests “steadfast protector with joy” or “guardian of joy,” carrying both strength and cheer.

Billie gained currency for both sexes from the late 19th century, becoming especially fashionable for girls in the 1920s–30s; figures like Billie Holiday and Billie Jean King kept it familiar, and recent pop culture has revived interest. Joy peaked mid-20th century in the English-speaking world. The hyphenated pairing fits a modern British and Australasian taste for double-barrelled names. Variants include Billie Joy (unhyphenated), Billy-Joy, Billie-Jo (distinct), Billie-Rose, Billie-May, and spellings Joye or Joi.
