Dog name help 😊

Elandra
This is Gianni, our all black Pomeranian. On Friday we are adopting his same breed and color, just a girl. This is her: 
The only difference is that she has some lighter hair in the back and Gianni doesn't. At the moment, her name is Kitty, which we absolutely hate. I chose the name Ella, and my SO chose the name Patches. Both of us like both names and wouldn't mind either way, but what do you think sounds better, Gianni &Ella, or Gianni and Patches? Or neither?
