Mary Etherington was an English horse breeder from Withypool credited with reviving the Exmoor pony population after World War II. She and her husband, (1906-1980) co-founded the at the Royal (Dick) School of Veterinary Studies now part of the University of Edinburgh. When Mary and her husband decided to sell the Herd 2 Exmoor ponies, the students who had been running the treks formed a syndicate and in 1962 bought a core group of mares. These were bred as herd two until the last foal in 2009.
