Hi Ken
Many thanks for that info.
Thomas was born in East Dereham, Norfolk, which is why I assumed the Norfolk Regiment.
I do have his discharge papers which gives all personal details such as birthplace, age, physical description, health etc. I'm also pleased to report he had a glowing writeup and gained 5 good conduct badges

(Unlike his son who was court marshalled and kicked out the army at the start of WW1, but that's another story!)
I confess to being puzzled why he joined Northumberland. He actually enlisted in East Dereham. I really would have expected Norfolk Regt. Ah well, guess I'll never know.
One other question please. As he signed up in Dec 1859 and doesn't appear to have left England until 1867 (in London and Woolwich in '64) any brainwaves as to where he may appear on the 1861 census? I'm assuming in barracks somewhere so any idea where the 5th had barracks at that time?
Thanks again for your help, most appreciated
Sue
