I had a look for you in the Newspaper Section of FindMyPast, but can't find an Entry on there.
Was she the Rebecca B. Waye, Born 1860, and so 57yrs at the time of Death?
Btw The British Newspaper On-line Site is always having '1 month for £1.00' Offers, and it might be worth you having a look on there. Inquests were usually reported in the Local Papers, but of course 1917 is during WW1, - when an unusual amount of Deaths were happening, - and so might not have been as well reported as per usual. One of my Uncle's committed suicide in 1930 and there was an Inquest, - the cause of death was ammended on the Death Cert after that. What does it say re: the Death on the Cert for your lady?
