Born in Stoke Newington, London, c.1834. [CHECK - perhaps Newington, Surrey?]
Enlisted at London on the 16th of September 1852.
Height: 5' 7".
Discharged, "time expired", from Hounslow on the 15th of September 1864.
In possession of two Good Conduct badges.
Entitled to the Crimean medal with clasps for Alma, Balaclava, Inkerman, and Sebastopol.
A supplementary roll (undated) signed by Major Henry Holden shows him as being issued with the Crimean medal (with clasps for Alma, Balaclava and Inkerman) on the 7th of October 1855.
PB, August 2020: After an enquiry by a potential descendant who believes his ancestor may be buried in St Arnaud, Victoria, Australia, I started to explore genealogical links but there are innumerable possibilities, and of course the variations in spelling of his surname don't help.
A number of Ancestry Family Trees (e.g. Dickeson Family Tree 2) make connections between the TD born Newington, Surrey (or nearby), the cavalryman TD, and the TD who died in Australia. In some, a photograph of a 4-bar Crimea medal is displayed as an icon. Others have nothing about military service, and appear to show different genealogies.
However, the military information they assert is clearly derived from the EJBA, without (so far as I can see) either citing the EJBA or providing any further supporting evidence.
1841: Thomas Dickenson, aged 7 [est. birthdate 1834] , and family [mother Jemima Squires], Camberwell, Surrey
1851: Thomas Dickenson, aged 8 [sic] [i.e. est. birthdate 1843] , scholar - clearly this needs some explanation (admin. error? different Thomas? death of first "Thomas" and a new child given the same name? etc)
Arrived on the St Osyth, age 42, travelled alone [no source cited].
Death 9 August 1894, St Arnaud,Victoria, Australia [no source cited].In short, needs a lot more research.
Would be good to check for newspaper articles in St Arnaud, esp. Obituaries? Try Trove.
