I love quirky and kind of ugly/so wrong they are right combos. I prefer
Jean Baptiste Rudy as a combo, because of how fun it is. And I prefer
Penny over
Penelope too. ( I think you are dead-on about the qualities of
Penny, it's so perfect as a full name, because it's so wrong!)
And let me say, I think
Elvis Larry is absolutely adorable. I imagine a really fun but sweet grandpa, makes my heart flutter to think of it on a little boy!
