hi , how easy would it be to find the actual name of this children's home on the census below?

I am trying to find the boy named Robert Johnston. I know he died 12 Apr 1874 and he is buried with some relatives but I have no idea who his parents were, there are 2 sets of parents that could be his.
I hope I have copied the link correctly

Kind regards Janette ( UK)
