we change nearly all of ours as we have a theme to our names (eg Damson, Quince, Medlar, Pumpkin, Nutmeg, Willow, Hawthorn, Parsley, Peaches, Bluebell, Mullberry, Teasal, Comfrey, Milk Thistle, Blackberry etc etc). there are so many choices in the tree/fruit/plant/flower category that there is one to suit every rabbit
Parsley is the only one we might have avoided as a name but we actually found him in the Parsley patch on the allotment!!! (he was a stray)
The only ones we didn't change were Florence who had been Florence for so many years in rescue - and also there is a type of Fennel which is Florence Fennel, and then Pansy who came to us a couple of months ago.
