Briar_pros's list "Cool tomboys" of 4 great name ideas: Jo - Will!

Cool tomboys

Girl names with a tomboyish vibe and a hint of cool to top it all off.

The name Jo still evokes the spunky image of the character in Louisa May Alcott's Little Women. Its literary status makes Jo one of the OG boyish nicknames for girls, ala Frankie, Billie, and Stevie. If you like that form, you can lengthen it to Joey.

The short but solid Irish surname Shea works well for both genders thanks to its soft, succinct sound. The traditional Irish form is Séaghdha, though it could also be used as a short form of Séamus, connected to James. 
 
Kevin James has a daughter named Shea, while Shea Coulée is a drag queen who featured on season 5 of RuPaul's Drag Race: All Stars. 
 For baseball fans: Shea Stadium was the home of The New York Mets until 2008, and has proved surprisingly influential as a namesake. Four of the players of the New York Mets named their children Shea in honor of the place, as did Jets player John Matlock and the aforementioned Kevin James. major League player Shea Spitzbarth also got his name from the stadium.
 
Another variation and the one that leans furthest toward the female side is Shae, for those who don't want the pronunciation confused with Shea Butter.
