The 'Hugh Wallis' index has a help verify the suggestions you made about possible James Callow's, and I have had a quick look at the Cumbria Archives site but will have to go back and explore that further in the context of Preston Workhouse records. Jane Quine's death certificate is our highest priority at the moment so will track that down for further information and see if we can move on from their. I may post a Jane Quine message and see if that brings anything to light.
