There was originally no information about this man in the EJBA.
When he started researching the field, Jim Boys included only those men he knew from records had actually arrived in the Crimea and were entitled to the Crimea Medal. He later accepted that this was too restrictive, but was unable to add all the men who embarked for but did not reach the Crimea. Many, for example, died en route at Varna, Bulgaria, where epidemic diseases such as cholera were rife in the camps. Others arrived too late to qualify.
The current editors are intending to include these men, and will be adding information as soon as possible.

[PB, Jan 2014: In her memoir, Fanny Duberly describes the suicide of a sergeant of the 8th Light Dragoons at Varna (13.7.1854), pp. 34-5. Although she does not name him, this must surely be Sergeant Hanna.]
"Thursday 13th July 1854
...A sad event closed this day. One of our sergeants, who had been ill for some days previously, left the hospital tent about three o'clock a.m., and, when our watering parade went down to the river, they found his body in the stream: he was quite dead. He was a steady and most respectable man: he could hardly have had a foreboding of the lingering deaths of so many of his comrades, and so rashly have chosen his own time to appear before God?"
