Where do American Cormo Sheep Come From?

American Cormo Sheep are originally from Tasmania – an island region of Australia that is a few hundred kilometers south of mainland Australia.

They were first introduced by breeders in the early 1960s and their lineage is owed to several breeds of sheep including Lincoln, Australian Merino, Corriedale rams, and Superfine Saxon Merino ewes. The name Cormo derives from a mix of Corriedale and Merino.

They were first brought to the United States in 1976 and the American Cormo Sheep Association was founded the same year. To be registered with the ACSA, purebred sheep must conform to all breed standards, and purebred American Cormo sheep are individually registered by name.
