Thank you all so much for this. I have no idea how you have managed to find all of this - and to be so generous in giving your time and to share the information!
JJ was there a date for the record you found giving his 'Holmlea' abode in Hem Heath? I located the property searching old maps which named the houses. It still stands and it's a tiny unassuming bungalow. Also just to add I have just found some records of planning applications for a few simple town houses made by Sherwin & Heath (the name of their practice before Alfred went it alone) as well as a factory in Crewe. This ties in with mention of his studying factory buildings in that record. I only found these after being given the cheshire connection - so thanks for that
Cherry Orchard Farm is in a completely different league which also still stands in Nantwich. That would perhaps tie into sheep breeding & horse ownership?
I just ordered the 1961 death certificate - £11 but it looks like the order has been sent to Cheshire East BDM who will then locate it, copy it & post it to me so it could take a little time to arrive.
I found a division of Cheshire East Council called Orbitas who have burial records for the area - I'll contact them on Monday.
