According to TMZ, who saw the birth certificate of Emma Stone and Dave McCary's baby, the newlyweds named their daughter Louise Jean McCary. Stone's full name is Emily Jean Stone and her grandmother's name is Jean Louise. A source told TMZ that the Academy Award Winning actress gave her daughter the name as a tribute to Stone's grandmother.

The name is a powerful one in more ways than one. Per The Bump, the name Louise has Old German roots and means "famous warrior." The Bump notes that Louise's middle name, Jean, means "God is gracious."

An insider told Us Weekly that Stone is a "very hands-on-mom" and has been enjoying spending time with Emily Jean. They said, "She's soaking in all the precious moments of being a mom for the first time. Her No. 1 priority is to raise a healthy baby, so that's what she's focused on right now. She's super protective as well, so she hasn't had too many people come visit yet." The "La La Land" star is also closer with McCary than ever before. Another source told Us Weekly that the director is "hands-on and helping with their daughter."
