I've found a grave in Newton-le-Willows Cemetery on which John William Jubson of the Royal Garrison Artillery is commemorated. The lower part of the inscription is badly eroded, but I can read that he 'Died on Duty Set -- 1901/ Aged -- years and was interred/ ....
Thanks for your efforts - I've just discovered that the records for the cemetery are online - and have found that the family name is JUDSON ... and that John William is not registered as being buried in the grave.
I'm recording for the IWM's War Memorials Register, which has a category for 'Additions to gravestones', covering family commemorations for casualties buried or commemorated elsewhere. Whilst scanning the inscriptions I'm tuned to looking for clues - and the mention of a military unit and a date fitting the years of a conflict make me stop and look harder - unfortunately the erosion on this grave makes it impossible to read further information which was once legible.
Just now I had a look at the Palmer Casualty roll (which is based on the official SAFF/NFF Casualty lists with all the imperfections therein) and there are a couple of JUDSONS;
(1) Judson, J (no rank shown) who served with Damant's Horse and was severely wounded at Tafel Kop on 20/12/01
(2) "2391 Pte.Judson, J of 1st York and Lancs Regt" who was wounded at Venter's Spruit on 20/1/00.
Regretfully, nothing for the RGA. Might help and might not.
I have found an entry on Ancestry regarding UK Army register of Soldiers Effects 1901-1929.

Not sure if this is your man.....will keep looking.
You only live once, but if you do it right, once is enough.
