I really love the combo
Francis Jonathan.
Francis is falling out of favor, so I'm happy to see it.
Jonathan makes it just a little stronger than
Francis John; I mean, I love
Francis John, but
Francis Jonathan is a more wholesome combo.
As for the nickname
Frankie Jack, I hate it. I think
Francis should suffice;
Frankie is a little weird for me...I already hate
Frank for being ugly. Besides...Frankie is considered the nickname for
Frances, so
Frankie's the feminine form of an already hideous name. Still, it's a good thing
Frankie isn't his birthname.
Is this couple American?
