Billye is an uncommon yet charming given name of American origin. It is a variant spelling of Billie, which itself is a diminutive form of the male name William. Billye is more frequently used as a female name, though it can also be used for males. The name's popularity peaked in the mid-20th century but has since become quite rare, making it distinctive and memorable today.
"Billye peaked in popularity between 1927 and 1930 with ten births each year, but has since declined, with only five births recorded in the years 1933, 1936, and 1943."
