I need to know if this sounds ok 
Dylan Jonah... 
We originally wanted to name him Daniel Julian 
But since my husbands and two other boys names have 5 letters he wants this baby to be the same 
So my husband decided he like Dylan and we're trying to find a biblical jo name that goes with it.. 
He said Dylan Johnathan 
I'm so confused 
and I'm due Wednesday for my c section
