You could try contacting the funeral directors, they may have a name for you. 
A few years back a distant relative died (only child, not married, no close relatives). I wrote a letter to 'the person sorting out things', put it in a blank, stamped envelope with my name and return address on it, brought it to funeral directors and asked if they could forward my letter to the person in charge of the funeral arrangements. The lovely receptionist rang the person who then gave permission for their name and phone number to be given to me. I rang and spoke to this (another) distant relative who had no interest in family history and said the house was full of old pictures (I suspect as much because deceased's grandmother had looked after her father in his last years). I was told a friend was clearing out the house and got his contact details.
Next, I rang the friend who invited me to his house to see all the pictures he'd saved. The sitting room was filled with boxes which he'd sorted and I was invited (well, begged almost) to take as many as I wanted as they were likely to get thrown out eventually. Came away with pictures of my mother-in-law as a young girl, her parents, etc. Also heard some lovely stories about the deceased whom the friend had known since they were children.
