ORMISTON, a surname derived from lands of that name, now a parish, in East Lothian. They were so called from an Anglo-Saxon, named Orme, who possessed them in the reign of Malcolm the Maiden. Whether this was the same Orme, the son of Hugh, who was abbot of Abernethy, in Perthshire, in the reign of William the Lion, and whose descendants, from his possessing the lands of Abernethy, assumed that name, is not known. There are various places in Scotland of the name of Ormiston.
