Early Origins of the Sly family

The surname Sly was first found in Essex, where Walter Sleh was listed in the Feet of Fines in 1219. Thomas Sleh, Slei, Slegh was listed in the Assize Rolls of Lincolnshire in 1219 and Robert Sley was listed in the Assize Rolls of Warwickshire in 1221. 1

The "epithet sly did not primarily imply anything dishonourable; though like 'crafty' and 'cunning' it has since come to be taken in a bad sense. The Slys or Sleighs were skilful men - cunning of hand. We are informed that Sly was anciently a common name in Shakespeare's own town. " 2 The Hundredorum Rolls of 1273 include: Ralph Sly in Hertfordshire; John Sley in Cambridgeshire; and John le Slege in Oxfordshire. 3

The hamlet of Ash in Derbyshire was an ancient family seat at one time. "The place was the property of the Sleigh family, from whom it came to the Chethams, and subsequently to the Cottons." 4

The British first settled the British West Indies around 1604. They made many attempts but failed in some to establish settlements on the Islands including Saint Lucia and Grenada. By 1627 they had managed to establish settlements on St. Kitts (St. Christopher) and Barbados, but by 1641 the Spanish had moved in and destroyed some of these including those at Providence Island. The British continued to expand the settlements including setting the First Federation in the British West Indies by 1674; some of the islands include Barbados, Bermuda, Cayman Island, Turks and Caicos, Jamaica and Belize then known as British Honduras. By the 1960's many of the islands became independent after the West Indies Federation which existed from 1958 to 1962 failed due to internal political conflicts. After this a number of Eastern Caribbean islands formed a free association. 9
