In the 16th century, Edenderry was known as Coolestown, after the family of Cooley or Cowley, who had a castle here. It was defended in 1599 against the Confederates, during the
Nine Years' War. This subsequently passed by marriage to the
Blundell family and was sacked in 1691 by the army of
James II. The Blundells' land passed subsequently to the
Marquess of Downshire, who reversed the earlier opposition of the Blundell sisters to the establishment of a branch to the Grand Canal to Edenderry and paid for the £692 cost of the project, which was completed in 1802. By 1716 the manufacture of woollen cloth was thriving, first established by
Quakers, which employed around 1,000 people. By 1911 the town had grown to 2,204 people. Other industries included the factory of Daniel Alesbury, who made a variety of woodwork as well as the first car manufactured in Ireland, the
Alesbury, in 1907.
Edenderry Town Hall was completed in 1830. ==Demographics==
