Gender neutral name for baby #3

No idea why we started naming our kids R names, but here we are very pregnant and scrambling for another R name for baby #3 (big sis is named Reagan, brother is named Roman). We’re waiting until delivery to find out sex, so having a gender neutral name ready would be nice but seriously open to anything. We even considered a non-R name, but then worried that maybe the third will feel left out? 🤷🏻‍♀️ In any case, open to any ideas as we are not 100% crazy about any names so far 😬
