Middle name help!

We’re having our 4th, second boy, next month and we’re stuck picking a middle name for this little guy. His first name will be Luca. We have a Madeline Annalise, Isaac Asher, and Olivia Eliana, so we’d like for it to fit in with his siblings names. Each baby for us has a biblical name so that’s where Luca comes in. We want something maybe not so common- also not opposed if it’s on the European side as I am Romanian.

No go names are- Michael and james.

PLEASE HELP!!
