Unique baby nibble name ideas

I want to surprise my husband and have the baby's middle name named after him. I have no ideas though. We both agreed we love the name Penelope, so that is her first name but we never thought of a middle name. I'm 36 weeks and this is my 3rd pregnancy, I had names picked out for my oldest 2 girls before I was even 15 weeks. And I'm feeling like it's getting to close to the baby's due date. Any ideas? His name is Andrew. My mom always jokes about it should be Andrea but I have like 4 friends with that name lol Help!
