Well, (whipping out my obscure book: "Rare Breeds: Endangered Farm Animals in Photographs", The Jacob (four-horned, indeed, and also known as the Spanish), ia "related not so closely to the British multi-horned breeds, such as the Manx Loghtan and Hebridean, ". If you had been in the American South-West, the option would be the Navajo-Churro, which is derived from the Iberian foundation stock. (I just love having weird reference materials right at hand!)
