Hi Valda,
It looks more and more like i shall have to contact the Nottingham archives and try and get his details if it is possible as to why/reason he was at the Hospital.
I would assume i am the closest of kin now as my dad was the only child, in regards of proof i have my birth cert with the details of my father and my fathers birth cert from 1926 which has his fathers and mothers details on it.I also have the marriage cert from 1919 of my grandad who was in the mental hospital.I would hope these would suffice to prove my relationship with my granddad,hopefully it would have been my grandma, his wife who would have been the next of kin on his details when he entered the hospital.
I have tried the Sutton in Ashfield cemetery site and upto a year after the date he died and there is no sign of his burial ,so it would appear he was buried locally to the mental hospital.
Once again thanks for your time and reply.
Malc.
