Name ideas! (Gender will be a surprise)

MyLittleButtercup • Mama. Wife. My girl is 6, my little miracle dude is 4, and my little smiley guy is 1! It’s been a wild ride! 🎉🤷🏼‍♀️

We have a June Austen and an Amos Andrew. Looking for a classicy name but not a common one that goes with those. I like Penelope, Calliope, and Freya for a girl. My husband is only a fan of Penelope. No clue for a boy. I’m not into any of the modern trendy names, in no way knocking those that are. Just looking for some ideas! ❤️
