Beyond, or a variant of Bianca meaning white
Beyonca is a modern American creative spelling, likely influenced by the name Bianca or the word beyond. While it shares phonetic similarities with the Italian name Bianca, which means white or fair, it is often chosen for its unique and contemporary flair. It gained some visibility in the late 20th century but remains a rare choice.
