Boy #5 - HELP!!

Em

I have 4 boys. There names are:

Israel Cole (Cole)

Elijah Jude (Eli)

Noah James (Noah)

Ethan Sawyer (Ethan)

I am 33w5d and have no clue what to name boy #5. Some names I've considered but haven't gotten my husband on board with are:

Jonah

Nicholas (Nic)

Titus

He likes Riley Parker, but I don't think it goes well with his brothers names.

Please comment with suggestions that go well with our other boys names!! You can put the names we've considered together and give other suggestions!!!
