Introduction
We present below an edited transcription of the 1821 Census of Castlerahan (Castleraghan) Parish, courtesy of the author, James L. Brady. This transcription and analysis of the census returns of the parish of Castlerahan was a project which was carried out in 2007 in fulfilment of the requirements for the NUI Diploma in Genealogy/Family History by the author. We would like to thank James for contributing this important work which presents the information held in the census returns in a useful format which adds greatly to our knowledge of the parish during this era. This work was added to in 2008 when the author prepared a similar study on the parish of Lurgan which can be viewed here.
