In fact, this is the guy buried in his grave;

6322 Rifleman Patrick Fitzsimmons, 2nd Royal Irish Rifles, KIA 16/6/15, age 35, the husband of Bridget Fitzsimmons, of 9 Raphael St., Belfast.

It appears that the MoD and the CWGC do not have the will or the bottle to do the decent thing and acknowledge the error.
