As Censuses are organised by Registration Districts, which do not necessarily correspond with county boundaries, a set of census records for a Registration District may omit some places within a county, and/or include places from adjacent counties.
This CD contains the records relating to Devon that appear in the Cornwall Registration Districts, and therefore are not listed in the Devon 1861 Censuses, they are however listed in the Cornwall 1861 Census (item GBC1861COR). So for those that want a 'complete' coverage of Devon (going by county boundaries), this is for you - buy this Supplement, and the Devon 1861 Census and it's all there.
Whole census pieces are included, and therefore the places included are those on both side of the county boundaries.
