Boy name suggestions that start with M!

So

I’m 4w5d with baby #2- Hoping for a girl since I already have a boy, but of course I’m team healthy baby no matter what!

I’m trying to stick with L M or M L initials- I already have a girl name picked out so I’m trying to choose a boy name, preferably a Brazilian name, because my husband is Brazilian.

I like the name Lucas but, Lucas what or something Lucas.. please help😅
