Names for my twins! (Boy and girl)

I'm 22 wks and still can't decide on a name for my twins!

We were thinking:

Gabriela and Gabriel

Jiovanny and Jiovanna (to go with my other 4 kids names)

*the only problem is their last name will be Garcia and I wanted to give my daughter a middle name that starts with an A. Her initials won't be that nice lol

* I have 4 other kids who names are J's

But im open to all names
