There is a probate reference to a Gertrude Eveleigh Muriel Birchall, who died at Paddington Hospital on 2 May 1940, widow, formerly of 11 Carleton Mansions, Maida Vale, London, probate to Richard Locke Bell, medical practitioner on 24 June.
Bearing in mind that her name is quite unique, I wonder if this is her?
Edit: I've found a possible Mr Birchall - Oswald - who was a lot older than her (29 years) and also died in Paddington in 1918. I can't find a marriage between the two yet though.. could the age of her husband be the reason she suddenly ships out from Lancashire to London (assuming it is her?

)
