Hi Jillynetter. Sounds like you've been having a long do with this one!
I'm a bit confused though. Was your husband in Carlisle Library or was this a national paper?
In other words, I'm not sure if it's just other ideas on where to look you need, or if you can't get into Carlisle. Also, do we know it's Carlisle
If you've got a date, the registers for the cemetery are in the library as well as the record office. I think you must have, but otherwise the record office has indexes as well.
If it is the cemetery at Richardson Street, and you get the grave plot number from the register, they have good maps and it's reasonably straight forward to find a plot, if you can get there. Then you can see if there's a stone with other information. The cemetery can also tell you who bought the grave.
I'm not sure if you're local and have that anyway or not. If not, if you get a number I'll go and look. Let me know if there's anything that will help.
Do you have easy access to Carlisle library?
I hope you move on with this. By the way, some events are reported or announced in more than one of those papers in there completely differently, so it's worth checking another.
Sorry, read again and you've given some of this. Emms
Best wishes
