Girls names

My husband will not budge on Amelia if the baby is a girl. My cousin (there’s only 2 of us) already had a daughter named Amelia. I feel like my grandma is going to get so confused. Not to mention I’m not sold on it. I really want McKinley or Ellianna. Any suggestions on how to get him to be more open about other names?
