Gnu,
I only have a copy of the marriage Certificate,
Hendon Register Office,Middlesex, 26th October 1920.
Annie aged 30 years, Spinster.
William aged 47 years, Widower.
She was down as a Daily Domestic and He as a General Labourer ( ex army).
The Death record online, I take to be hers, because she died in 1979, aged around 90, family remember it to be around that date, when she was cremated at Golders Green Crem, and the record gives birthday as 13.03.1890, which would seem to agree with stated age on Marriage Cert.
Thanks
