I am trying to find info. about the origin of the surname Coelho. I already know it is a name that came from the Spanish territory ( Coello ). Somehow, and due to some marriages in Portugal, mainly in the North ( Beira-Alta ) this name suffered a linguistic change to the portuguese form.
So, instead of "Coello" it was transformed to "Coelho".
If anyone knows more info. about "Coelho" or "rabbit" in english feel free to say something.
