I am looking for information about my grandfather's sister Edie, I don't have any date of birth or death for her.
My grandfather, Ernest Smith was born in Manchester,1917 ?
Ernest isn't alive. The whole family moved to Nottingham.
When & Where did he die?
If the death is after Jun 1969 it should give his dob that might help narrow down his birth registration.
Have you found him on the 1939 Register this will also give his dob?
Have you found him on 1921 census?
For info. as an example there's an
Ernest SMITH b1917 Manchester free info. available shows he's with
James & Caroline Smith plus 6 others - using the advanced search it appears that James Smith b1864 West Brom., Caroline b1872 no pob given and I think the other persons are:- James Harold born 1892 Egypt, John William no pob, Bert, George Harris & Winifred born 1913 Manchester - NO Edie/Edith though

As mother was born in Spain possible birth entries for Winifred & Ernest

Looking at the 1911 census it looks as if James Harold born Egypt's middle name is Horatio

Caroline Smith married 25 Gibralter
James 9 Egypt (British Subject)
Caroline 7 Manchester

Caroline 38 Spain
James Horiatio 18 EgyptMary Caroline 16 Manchester
Ann Maira 14 Litchfield

I’m assuming that Edie was born around 1920 if she helped Jewish families settle in the UK during WW2. There is this registration in Lancashire.
SMITH, ERNEST HALL

Births Dec 1920
Smith Edith F Hall Leigh 8c 496
Edith was the only Smith registered in Leigh 1915 - 1925. There are several other Smith’s mother Hall registered Nottingham after 1920, so maybe they first moved from Manchester to Leigh, then Nottinghamshire?
From GRO indexes Edith's middle name is
FlorenceOn 1921 census Leigh Lancashire there is a
