I have found a death for a James Turnbull on 7th Feb 1872 aged 54 years registered at Lasswade, Edinburgh, Midlothian with the informant being his son William Turnbull.
My James had a son called William.
However, the writing on the death register is nigh on impossible to read despite my valiant attempts at enhancing the image. I can't read his occupation although it begins with F (too short to be furnaceman or foundryman).
Also I can't read the place of death ..... it looks something like Durden or Dresden House.
Anyone got any clues re the place of death or can anyone fathom out the writing ... am currently searching to see if I can find a different William Turnbull with a father called James but am crossing fingers that this is the right one and he was working away.

Come on Tom lets see if you can solve my last piece of the puzzle seeing as you did so well last night.
