Super conflicted. 4th baby due 6/10 and can’t decide

We have our 4th baby arriving soon and just can’t decide. We’ve narrowed down to the above two names. Has to start with J and flow with the other babes names. My first son is named after my husband but the rest of the babes will be J for my late mother and father and grandparents. My dads name was John, but I don’t feel right using John because my brother is John III. But I felt Johnathan was safe.

Middle name will be Frederick for husbands late grandfather.

Currently have:

1. Stephen James

2. Juliana Rose

3. Jordyn Olivia
