Tim has sent me a puzzle that I have not been able to solve and so am hoping that the super sleuths here can. 
Tim says, "I’ve had this silhouette for some years but Mr R Stubbs is not recorded, only that he was in Doncaster...I’m guessing date wise the profile was drawn maybe 1830/1840....might be a tad earlier....so Mr Stubbs might have been born in the late 18th century ?
Of course he might not be from Doncaster but possibly that neck of the woods."
The back of the silhouette:

All help gratefully received.
