Hi Bonnie
The burial register for Dalston Road is in the record office and also Carlisle library.
They might send you the details if you have give or take an exact date. The Cumberland News might also have carried it. There may have been an inquest too. That might have been reported and there is also an index of these in the record office. I think if you know the date etc they will do look ups for a small amount. Someone might be going up.
I'm afraid I can't get at the moment. you won't need it if you've got a date, but there's a cemetery index in the record office too. I looked at an incident in WW1 which was local and it was in the inquest details and also the local paper.
I can look at the grave for you, as I live close by. butI'll pm you.
By the way, the registers won't give the purchaser of the grave, or others buried there, but in this case, it may be a war grave and he may be alone, and also, we don't have the deep graves as in Lancashire and places - they are mostly just for two people., so you won't get hoards of relatives anyway.
I was also told by the War Graves Commission when I was researching a friend's relatives that if it were possible, such as a death in the UK, the family would have a choice of returning the person home, or burial "where they fell". So it may have been arranged by the forces.
Best wishes
