Boy names

So we just found out we are pregnant with #6 (I have one from a previous relationship, he has three and we have one together) my four all time favorite names are off limits (2 my sister took and 2 are his boys names) we are fairly certain it's a boy (this is number 5 for him and he has all boys) and he hates all the names I've suggested. He picked our sons name. I k ow it's still early but I like to be prepared and to be able to put a name to the gender reveal ultrasound. Any ideas?

Mason, Gavin, Tyler, Dylan, Robert and Cayden are all out of the hat because those are the ones mentioned before.
