Margaret Walmsley the address given for her on the pension index card was 29 Lawson St., Preston.
I've now poked round the electoral registers and found that a John Walmsley was registered to vote at that address in both 1911 and 1914.
Looking on family search for Margaret Walmsley in 1911, living in Preston with a Dad called John gives this transcript.
https://www.familysearch.org/ark:/61903/1:1:X49W-8GFFS don't include an address in the transcript but if you have access to the 1911 census there's a very high chance that the address will match :-)
The following is straw clutching as a possibility that couldn't be proved without further documents such as birth/ deaths certs.
GRO site gives a birth in Q2 1913, Preston for a Maria Walmsley, mother's maiden name is blank which indicates the child was illegitimate
Sadly there is a corresponding death in the same year and quarter for a Maria Walmsley age 0.
?a possible child of Matthew Wignall and Margaret Walmsley?
As I say, its straw clutching, but IF it is correct it could be a link between Matthew Wignall and Margaret Walmsley. Maybe they had planned to marry and he hadn't got home to do so before he was shipped off to France?
If it were me, I'd bung it in the possibles file anyway to be investigated at a later date (perhaps after winning the lottery - at which stage I could sit and order certs for everyone I have in my tree, no matter how tiny a twiglet they are!)
