Mary was the daughter of the Rev. Francis M(a)cDonald Etherington, and his wife Diana Gordon of
Sevenoaks, daughter of
Robert Gordon; they were married in 1899. Etherington was a theology graduate of
King's College, London, vicar of
Minehead from 1899 to 1914, of
Lenham 1914 to 1920, of
Stowey 1924 to 1926. He retired to Withypool, and died in 1961. Originally Herd 2 of Exmoor ponies, as it is now known, was bred by F. G. Heal, in 1930 a pedigree breeder at
Exford, Somerset of
Exmoor Horn sheep. He was Frederick George Heal, a son of the noted huntsman
Arthur Heal, and died unmarried in 1932, aged 75. Heal left the ponies to Diana Etherington. At the
Dunster Show in 1937, Mrs F. M. Etherington of Withypool won a prize for a moorland pony. In 1943 they were split between her two daughters, Mary and Joy, with Mary taking Herd 2 and Joy taking Herd 3. Mary Etherington was therefore responsible for the breeding of Herd 2 Exmoor ponies, after they were left to her by her mother. ==After World War II==
