Research the other names on the same census page. Some will have served in WW1.

Hmm. Interesting.

So far only one of those names looks helpful - Albert Stopgate. The 1911 and 1921 censuses show only 1 chap of that name of military age, so the guy on the 1921 of that name (Albert Stopgate, 23y 11m, b Cwmbran) must surely be the guy of that name in the Medal Index Cards:
S Wales Borderers 23476
Bedford R 43673
S Wales Borderers 80291

Albert is the only "single name" so far - one or two of the others match names in the SWB but I'm in danger of confirmation bias since there are several MICs for each of those names in different regiments.

The Monthly Army Lists for July and December 1921 show the 2nd Battalion SWB at Jhansi. Not sure that's helpful in that Jhansi isn't a place in the TNA Catalogue description of RG 15/28121, the 1921 census piece in question.

So now I'm wondering if S Wales Borderer 82331 Purcell Charles H might actually have been him... He seems a bit young to have accumulated 3 different numbers for a Medal Index Card but who knows?

I suspect I'll have to park this until the SWB's records get to Kew...

Thanks for the ideas guys.

Charles Henry Purcell on the electoral registers from autumn 1921, St Paul, P B of Blackburn.
That him? Was he an absent voter?

That's him - though you got there before me - because the rest of that household is his family. Unfortunately (and I think I've tried this before as well), I can't locate the Blackburn Absent Voters lists in those years that he's marked up as being absent. FindMyPast doesn't have a separate AVL for Blackburn (unlike, Crewe, say) nor are the absent entries for those years at the end of the book as they are in some constituencies in later years.

Thanks - I'm sure that there were lots of battalions in India in 1921!    Ideally, if there isn't some data in the census that I'm missing, I was hoping for a list somewhere that says what was at Chanbattia / Chaubattia, maybe something akin to the reports on Stations of the British Army that appeared in newspapers before WW1.

Thanks guys - my suspicion was that "Baden Powell Scout" was more of a description than a unit title but what it actually referred to, I had no idea, so thanks for the details.

In the South Africa Constabulary medal rolls there is a Trooper 3rd Class E Duncan E2802. Discharged by purchase. 1901 and 1902, Cape Colony and Orange Free State clasps.

Thanks very much indeed - eventually I found the rolls are on TNA Discovery's Digital Downloads - WO 100/273 for South African Constabulary: "E" Division and Miscellaneous should anyone else come across this post and want to know.

Now all I have to do is try and figure out if he is my rellie - birth details and father look promising...

From https://forebears.io/england/devon/tiverton (a historical description of Tiverton)

"A Home for children afflicted with incurable diseases has been established in a farmhouse, known as “Fire Beacon,” and standing on a hill overlooking the Exe valley, about. 2 ˝ miles north of the town: the inmates are ten in number; the Home was instituted and is maintained at the sole expense of Mrs. Unwin."

"Mrs Unwin's Home, Hayne, Tiverton" is then referenced on http://www.childrenshomes.org.uk/list/Devon.shtml?LMCL=MtBmBf of Peter Higginbotham's "Children's Homes" site, but no more details than the address are given there.
