Information about this artist was submitted in May of 2006 by Christine Sadler of the United Kingdom:

The spelling of his name varies, but Malbon is the one used most frequently.  However, on his death certificate he is named as William Molborne.  The certificate shows that he died on 25 February 1877, aged 72.  His occupation is described as Artist.  Cause of death was paralysis.   His niece, M. Ellis, was the informant and her address is given as the same as Malbon's, i.e. 12 Pear Street West, Ecclesall.
 
His baptism was 31 January 1809 at St Mary's, Nottingham, although I'm not sure where I got that information from - the IGI maybe.
 
His second wife, Hannah, I believe was one of my ancestors.  If that is the case, then her maiden name would have been Renshaw.  I have her death certificate and she died 5 September 1879 aged 79 years.  She is described as Widow of William Malbon, Photographer.  Cause of death was Decay.  The informant was Mary Oldham of the same address, i.e. 75 Cavendish Street, Ecclesall Bierlow, Sheffield.
 
My great-great-grandfather's will mentions two of Malbon's paintings:  Boy and Bird and Horse picture with Patridges.  These were left to my great-grandfather but I'm not sure what happened to them.
 
In 1877 Malbon and his wife (Hannah) were on poor relief of 4 shillings a week.  Unfortunately, records of poor relief for this area and date have been lost.  I got this information from a newspaper article:
 
LETTER TO THE SHEFFIELD & ROTHERHAM INDEPENDENT NEWSPAPER - 30 January 1877
"A SAD CASE
To the Editor:  A few days ago I visited the Museum in Weston Park, and amongst many admirable paintings, I saw one a very simple subject (three apples and leaves) painted by Malbon.  The sweet colouring and masterly finish reminded me of his works many years since, when contemporary with Martin Ward he produced pictures of great merit.  At this moment I have a very pleasing recollection of "The Thief Detected" and many more, all of which exhibited no oridinary skill of hand.  I tgurned away pleased with the sight of this smal picture, which is a gem in art.
A few days afterwards, having to pass the residence of Malbon, I thought I would call and see him.  I rapped at the door, when a strange face made its appearance.  I made enquiries, and heard to my great sorrow that the painter had been confined to his bed for sixteen weeks, and that all he and his wife (who is also ill) had to subsist on was four shillings per week allowed by the parish.
Mr Editor, I feel sure in this day when so many of our more fortunate townsmen are doing all they can to relieve the sufferings of the sick and administer to the wants of the wretched, they would be inclined to stretch out a hand to save this poor unfortunate artist from a pauper's grave.  Trusting you will give publicity to this painful circumstance, I remain yours respectfully.  HELP"
