Wymeswold is in Leicestershire so I have asked the moderator to move your post to the Leicestershire board.
born in the 1800's,
The 1911 census has 2 entries for Leicestershire with an occupation of Butcher - George Harold Walker b 1880 & George Walker b 1895
You have no info as to his birthyear or birthplace & appear to be seeking living relatives to pass the photo to. Rootschat has a strict no living persons policy to protect peoples privacy
Sophie Gertrude Firman was b 1873 in Nottingham so if George was a "special relative" you would have to research her FH to find a connection to George Walker then track George to find a marriage & children.
Given the timescale - to find living relatives could be very time consuming.
Have you checked the 1921 census or the 1939 register for him?
You could also try checking Trade Directories for him
