To do that you will need to purchase some certificates.
The 1927 (Robert E Foreman + Lydia Ingarfield) marriage for starters.
I also believe that the Ealing marriage wasn't in 1939, given the groom was b 1928.
Florence Gilham and George Hamerton did not wed until 1948.
If you search the 1939 register, it implies that Rena/ Renna Violet was b 1932, and was living in 1939 in the Bletchley area.
There is a birth in jun 1/4 1931 Greenwich which may be relevant, if Rena didnt like her "official " first name
