Bev is also a nickname for someone who has the Bevilaqua surname, like Andressa "Bev" Bevilaqua, who plays Rainbow Six Siege for Fury Global in the Women's Circuit of Rainbow Six Siege Brazil. She is a manager and sixth player for the team.
Bev was the name of Mrs. Bighead (one of Rocko's neighbors) on the cartoon Rocko's Modern Life. She was a frog. Not necessarily famous, but that's my first association with this name.
