I love naming my pets... some get nice names, some get corny ones!
The leos I have now are named Girl, Freckles, Boo and Candy. My snake's name is Bandula.
In the past I have given my pets these names: Basil, Zoe, Bo, Baby, Darwin, Daisy,Ursela, Andre, Eva, etc. Sorry there aren't any 'pair' names, but I hope these might get you goin'!
