The introduction of rabbits to England post-dates the Norman conquest.
I find it hard to believe that the romans didn't bring rabbits with them. Also, given the fullness of time, it is hard to believe that rabbits didn't ever catch a ride with any number of pre-roman visitors.
Right, commoners would initially only have known them as exotic burrowing hares.
This contradicts the article.
And the word rabbit comes there from french rabotte which however comes in turn from a Germanic language (dutch) so it doesn't feel quite french.
