I can only find two Humphreys in the RA medal rolls both with the initials of J.
One 1533 J Humphreys N Battery 6th Brigade deserted so unlikely to be him looking at his military record in the newspaper article.
The other one is the chap in the title. A letter T could easily be mistaken for a J when transcribing records. [You must be registered and logged in to see this image.]
