Selkirkshire or the County of Selkirk (Scottish Gaelic: Siorrachd Shalcraig) is a registration county of Scotland. It borders Peeblesshire to the west, Midlothian to the north, Berwickshire to the north-east, Roxburghshire to the east, and Dumfriesshire to the south. It derives its name from its county town, the Royal burgh of Selkirk.
Until 1975 it was one of the thirty-three administrative counties of Scotland, with a county council formed by the Local Government (Scotland) Act 1889. Under the Local Government (Scotland) Act 1973 the use of counties as local government areas was abolished across Scotland, with its area becoming part of the Ettrick and Lauderdale district of the Borders Region. Unlike many counties, Selkirkshire has not continued to exist as a lieutenancy area, but has become part of Roxburgh, Ettrick and Lauderdale for these purposes.
In the 1st Century AD Selkirk formed part of the lands of the native people who hunted it rather than settled there. Neither the Romans, Angles, or the Saxons cleared much of the forestry there and for centuries Selkirk was known for its forest coverage. Indeed an alternative name for the county was Ettrick Forest. Under the Scottish kings the forest was regarded as Royal. Despite this it was not until the reign of James V that sheriffs were appointed to administer the county on the Crown's behalf. Under Edward I of England, the forest was granted to the Earl of Gloucester. Later, the Earl of Pembroke assumed the hereditary sheriffdom. Under and after King Robert the Bruce, the Earls of Douglas, and later Earls of Angus administered the county on behalf of the Crown, until the Union of the Crowns.
Selkirk (February 19, 1988 – January 3, 2013) was an American-bred Thoroughbred race horse and sire who raced mainly in Europe. Bred in Pennsylvania and owned by American philanthropist businessman George W. Strawbridge, Jr., he was trained by Ian Balding. At the end of 1991, his third year, he had a record of 3-1-2 out of seven starts. In total, he had won six of his 15 starts. He retired from racing in 1993 and began his stud career at Kirsten Rausing's Lanwades stud farm in Newmarket, England, where he sired 92 stakes winners from 987 foals. He died on January 3, 2013 at the age of 25.
Selkirk was a chestnut horse with a white blaze and long white socks on his hind legs, bred in Pennsylvania by his owner George Strawbridge. He was sired by Sharpen Up, a British racehorse who won the Middle Park Stakes in 1971 before becoming a successful breeding stallion. His other progeny included Pebbles, Kris and Diesis. Selkirk's dam, Annie Edge was a successful racemare for Strawbridge on both sides of the Atlantic, winning the Park Stakes in 1983, and the New York Stakes a year later. Strawbridge sent his colt to be raced in Europe and trained at Ian Balding's Kingsclere training facility near Watership Down, Hampshire, England.
