I am trying to find out what happened to Raymond Leslie Randal Slacke, born 1908. Son of Raymond Randal Beresford Slacke and Edith Mary Thwaites. I have details of marriage and children and possible grandchildren, but I have lost the trail after the mid 1960s when all records seem to dry up. I understand that he may have worked for the british coal board as it was.
I am trying to find out if he is either living or deceased but I am unable to find any records online of possible death.
can anyone help or give me some suggestions on where to go next.
