I have his Will which was dated 1st October 1839 and it was sworn on 24th February 1840. I presume from this that his death was sometime in between these two dates. As his death was pre 1841, he isn’t on a census. However, as it was after 1837 it means his death should have been registered somewhere.
There are numerous clues about the possible place of his death.
From his Will we know that he had property in Islington - sometimes described as Middlesex, sometimes London. Another possible clue is that one of his executors was his business partner who lived in Wolverhampton.
We also know from the Will he was married to Sarah and they had three children, Mary, Sarah and Annie. I know from the marriage certificate of Mary that her father was a Carrier which probably means he could have been travelling around the country on his horse and cart when he died and, as his death would have been registered where he died, his death certificate could be anywhere.
His daughter, Mary, was born in Worcester in 1818 but married back in Islington in 1841.
Although it doesn’t necessarily follow, he had a three page Will which generally means he was probably quite wealthy. This sometimes means his loved one's may have put a notice in the local newspaper about his death. I have searched those newspapers which are online and haven't found anything about him at all.
With so many clues it seems a search for his death shouldn't be too difficult but I have searched for a while without any sign and am beginning to think it is unsolvable.
If anyone reading this has any thoughts on where he might have been, please add a comment.
