Kilmore or Killmore (Irish: "an Chill Mhór" , meaning "the big church"), locally pronounced 'Kilmoor', is a village and townland in south County Wexford, Ireland, about 16 km from Wexford town.
 Kilmore has a number of claims to distinction, including the tradition of carol singing in the village church at Christmas time, which has been taking place for over 200 years.
 The history of the Kilmore carols can be traced from the mid 18th century to the present day.
 They have been sung without a break since they were introduced to the parish by Very Rev. Peter Devereux, who was Parish Priest circa 1751.
 Some of them were written by Very Rev. William Devereux, P.P., Piercestown, a native of The Ring, Tacumshane, where he is buried.
 The remainder were written by Bishop Luke Waddinge of Ferns.

 He spent much of his reign reforming royal administration and common law.
 Through an extensive legal inquiry, Edward investigated the tenure of various feudal liberties, while the law was reformed through a series of statutes regulating criminal and property law.
 Increasingly, however, Edward's attention was drawn towards military affairs.
