Another boy...need a first name...

Hello! I have a question to throw an idea of first name which I have another baby boy due in June end of the month. I already have first son, almost two years old in March. His full name is Everett Mason Summerlin. So myself, Miranda. My husband, Stephen. So I will like to have something unique, rare, cool first name for second boy. So any ideas? His middle name may gonna be Marlin after my brother's passed away. Thanks!!!
