Baby name help please!

I have a McKinley (girl), Ronan (boy) and an angel baby named Fiona. We have another baby coming but don’t know the gender. We like the Irish/celtic theme we have going but are okay with other names too outside of that. I love Teagan and Regan but don’t want rhyming names. And we do t want anything too common but also something leaning traditional. Any suggestions that would go with our current babies would be greatly appreciated! 🫶🏼🥰💗
