the 1841 onwards work very well I ise 41,51 and 61 - suggest you use Foxit pdf reader and not the one by Adobe which has too many security failures.
Beware the printed 1851 issued by IoM Fam Hist as they are transcriptions from the local copy made of the 1851 census - in a few parishes the transcription is very poor and does not appear to have been checked (I understand that the problems with this publication was one of the reasons for Brian to make his own index)
