Without more information we may not know who this is.
Although understandably researching burial location alone may not give a true indication of where another may be, I was looking at data for Smith defenders.
Looking at the information in the forum's we have a burial location for George Smith 2-24/1387 Islington, so maybe not him, in relation to the location information in the article.
But we do not have, that I can find, a burial location for John Smith 25B/1005, parhaps this may be him.
Obviously this could relate to other Smith's posts.
Just a suggestion, but more information required of course.
