I received a reply from the registry today and the CR chap said they were going to recall the record book (2 weeks) to see if they can send me an improved image. I only mentioned the refund thing to highlight that I would like something for the money! Not that it was so dear, if the currency converter was right.

The index gave the age and name of father (not known). The age was a bit older than I would have expected, but I'm hoping that there will be other information to confirm if that was significant or not. To be honest, any Cavendish from the Isle of Man showing up in Australia is going to be one of mine! In another family line I have been researching, an extremely elderly widower, probably in his dotage, died in the workhouse (in England). I have no doubt he is my man because of other evidence but the age was quite wrong - possibly no-one knew and just guessed.
