Hello
There isn't an obituary or death notice jumping out at me from the British Newspaper Archive, but the address is just over a mile from the Southern Necropolis. There's no matching record for James in the Southern Necropolis on Findagrave, but it could be that there isn't a headstone or the indexing is still incomplete.
Do you have any information on the dates/places of death for his parents or any places they may have lived prior to Annette Street? If they had a previous bereavement and already had a grave plot somewhere else, they might have used that.
The Glasgow City Archives hold the burial registers for the time period you are looking for, so it could be a matter of trawling through them to see if you can find him. I'd start with the Southern Necropolis, and then any cemeteries near to any other addresses where Charles and Margaret might have lived since their marriage.
Sorry I can't be more help!
Best wishes
