Billiejoe is an uncommon, unisex given name of unknown origin. It consists of two parts: "Billie" and "Joe." The first part, Billie, is a diminutive form of the male name William, which means "resolute protection" or "strong-willed warrior," while Joe is a shortened version of Joseph, meaning "God will increase." Therefore, Billiejoe could be interpreted as "Strong-willed protection will increase." Alternatively, it might be considered an entirely new creation, not derived from any known names.
Billiejoe was quite popular in 1980 with 6 births that year, making up all of its total recorded births.
