hey i know this is a little bit of a late input. but i`ve had:
George, Joe, Penelope, and i can`t decide what my next one should be...
but yes those were mine. I think the name depends a lot on:
a)the personality of the cello
b)the look (yes they DO matter)

c)and personal preference is always important;you don`t want to name your cello a name that you hate. that`s just wrong
