Name for baby boy

Yanika • Mom of the best boy in the universe:)
About 4 weeks ago we found out we are having a boy, and my mom started to attack with with her favorite name, she wants me to name my son Leo., because when she was pregnant with me her mom asked her to name me Yana, which she did.  I am not against about Leo., but I was thinking for the middle name that may go with it and sound ok and can't think of any ideas.. My creativity is also sleeping because I can't think of any other cool names, my favorite name used to be Mark but my best friend just called her son mark, so i feel lost and confused.  My hubby feel the same way., whenever we open apps with names the only reaction we expressing is "I don't like this, I don't like that..."  I've never thought it will be that difficult for me, thankfully I still have time till last week of feb;)
