John Burr Painting

 The sketch name/title (A boy and Two Adults in an Interior) Displayed in London 1875

The Painting (John Burr 1876) name/title  (I BELIEVE THIS TO BE ONE IN THE SAME)

It was taken out of an old beat up frame to get pictures to post. My research has lead me to believe this is a true original is there anything you could tell me about this painting? The sketch attached to this email was drawn by John Burr in 1875  it was called " A boy And Two Adults in an Interior" I found this sketch online and it is located in London at the Royal Academy Of Arts. The sketch was given to the London Royal Academy of Arts by (Lady Orchardson in 1916) The sketch was sketched with pencil on wash wove paper. I thought the child was a girl but they didn't wear paint or overalls in those days. When I found the sketch I realized the child was a boy.

Now please view the attachments of the paintings and signatures. My belief  is the painting is of this sketch 1875, John Burr painted in 1876.....modified somewhat with furniture and such. There is just to much likeness. None of his other art work is to close in nature. I have searched his work and this painting is not anywhere online for me to believe it is a copy.
I have shown some close detail in these pictures so you can see the paint rolling at the bottom of the painting which also leads me to believe it is in fact authentic.  The signatures are from the same there is no doubt whatsoever. Now if this were a copy. Where is the original? It surely isn't online or any museums or art galleries, and knowone is selling copies of it. As they are all of his other work. I do believe this is the original. Any information you could give me or lead me in right direction would be greatly appreciated. I would like to know who the people were and the value of the painting. Please email me at [email protected] if you have any information or questions.

Good
