While tracing my maternal tree I remembered the stories my grandmother used to tell me about her family (Hardy/Haigh/Challand from Nottingham and Yorkshire). One was that her great grandfather ran with the highway men on the road south from Yorkshire and of course as a small child I found this fascinating and believed every word.
When I reached the appropriate generation I could find no evidence to support the story, although not sure what I would expect to find as no-one is likely to declare such an occupation on any census etc.
But one thing she failed to mention was that her grandmother was "famous". Mary Ann Challand (1838-1903) worked as a "clairvoyant" in Captain Hudson's mesmerist show. However, her claim to fame was to use her gift to find the body of a young girl who had fallen into a swollen river in Huddersfield

So the moral of the story as far as I have learnt is - never take anything at face value, listen to the memories you are told but still apply the same amount of rigorous research to verify them.
