Bix

Bix entered the lexicon as a girls' name via heroine Bix Caleen, played by Adria Arjona, on TV's Star Wars prequel Andor. While Bix is a new name for girls, it's been around for decades for boys via jazz musician Bix Beiderbecke, and Bex is a trendy nickname for Rebecca as well as a short form of the also-trendy Bexley (and Bexlee and Bexleigh).
