Damn, I just deleted a long post about a possible for Evelyn because I couldn't prove any of it, but immediately after that I found the link I needed! So..,,...let's try again (at least this time I can put it down in chronological order!)
Births Jun 1912
Horne Evelyn M A Montgomery Chertsey 2a 121
bap gives dob as 2 May 1912.
(here's the bit I found just now
Evelyn Mabel Annette Baker (adopted) dob 2 May 1912 born at Addleston, Surrey.
The above appears on a service record that has the top edge missing so I can't see the name of the soldier, but luckily his wife appears as:
May Baker (her surname is Baker in the nok box and as her maiden name!) married 28 Jul 1910 at Addleston.
There's no May Baker marrying in Chertsey district in Q3 1910 so I looked for May X marrying X Baker and found:
Marriages Sep 1910
Baker Albert Chertsey 2a 73 <<<<<
Ingram Annie Chertsey 2a 73
Montgomery May Chertsey 2a 73 <<<<<
Smeeth George Chertsey 2a 73
So presumably May is a relative of Annette Montgomery! (sister?)
Then these are the bits I posted earlier and deleted:
Marriages Dec 1938
Baker Evelyn M A Hainsworth Leeds North 9b 657
Hainsworth George Baker Leeds North 9b 657
Those two are together on the 1939 register with her dob correct.
and Evelyn's death:
Name: Evelyn Mabel A Hainsworth
Birth Date: 2 May 1912
Date of Registration: Apr 1985
Age at Death: 72
Registration district: Leeds
Inferred County: Yorkshire
Volume: 5
Page: 299
Here's May Montgomery and Albert Baker in
1911. Her age and place of birth match May Montgomery in 1901 though I haven't actually looked to see if Annette was in that household or an earlier one as I have to go out soon.
