"This parish is circumscribed by the parishes of Crosby, Scaleby, Kirklinton, Hayton, Brampton and Walton, and derives its name from the Irthing, which flows at its southern extremity. It is intersected by the site of the great Roman Wall, and also my the military road from Newcastle to Carlisle. It is divided into the four townships of Irthington, Laversdale, Newby and Newtown." [Description from T. Bulmer & Co's History, Topography and Directory of East Cumberland, 1884]
"The church, dedicated to St. Kentigern or Mungo, is a good specimen of Norman architecture, and is the principal object of interest within the parish. The original edifice was a plain building, erected about the twelfth century when the Norman style was beginning to give place to the more ornate Gothic. The church was thoroughly restored about thirty years ago [Ed: from 1884], the cost raised by subscription." (Extract from Bulmer's 1884 History & Directory, cited above)
Irthington fell under the authority of the ancient diocese of Carlisle and wills prior to 1858 were proved in the consistory court there. Records from 1548 to 1858 include original wills, letters of administration and inventories, although there are significant gaps in the years before 1661. These are deposited with the CRO at Carlisle. Comprehensive indexes exist, at the Carlisle CRO, in card files easily accessible in the reading room. The indexes cover from 1617 to 1941, listing the year of probate and the residence of the deceased. This is extraordinarily helpful in distinguishing between many individuals of the same name. Microfilm of many of these records, and a partial typescript of the indexes, is available at the Kendal office of the CRO.
The Province of York covered most of northern England, including this parish, and anyone who died leaving property in more than one diocese within the province would have their will proved in the Prerogative Court of the Archbishop of York (PCY) or sometimes in the Chancery Court of the Archbishop of York. These records are now deposited with York University, Borthwick Institute of Historical Research.
