What is the date of death - I don't have access to Ancestry so can't see what you're referring to 

If it is May 1866 here is the burial (the place of death is also on Durham Records Online free index as Palmer Street)

if this is your man where is he in 1851 and 1861?

Crucifix Lane.
There is a newspaper obituary in 1923 for Joseph Egan of Egans wine & spirits merchants of 9-15 Crucifix Lane.

Just one or two other things I have found.

1. A free search on SP shows the Schulmans were still in Aberdeen in the 1911 . As well as David and Annie there is a 5 year old Eva Barrett Schulman. ( Unable to find a birth for Eva).

2. There is an article in the Lancashire Evening Post 6 April 1921 about an Annie Shulman of 83 Chorlton Road, Manchester who was charged at Manchester County Police Court with pretending to tell fortunes. The defendant called herself Madame Barrett.

May I suggest that the 17 page thread to which Bridget has linked is read thoroughly before doing any more investigations about Annie. Both the 1911 census and the newspaper article you mention have already been noted there.

The record shared below of a John Williams Chambers placed in a Northumberland workhome is local to the father, John Chambers who died in the Morpeth workhome.

If this is the case, then John William Chambers was placed in the Reformatory (not 'workhome') some time before 1895, when this particular John Chambers died. Do you have evidence of this?
Given that this was a place dealing with boys who were regarded as 'criminals' and 'delinquents' I think it's most unlikely that any consideration would have been given to placing him near his father.

He was certainly placed there in mid-March 1901, (i.e. very shortly before the census in which he appears there) having been found guilty of theft (see attached snip).

I have to agree with Neale that the evidence suggests that the John Chambers whose death you've found in Morpeth looks very unlikely to be the one you are looking for. If I were you I'd definitely purchase the 1894 Gateshead death certificate.
