Beatrice Newman death

[EdCan]

I am having a hard time trying to find the death of Beatrice.
She was born Beatrice Edmonds Bayliss 13 Mar 1883 and married Walter Daniel Newman 6 Jan 1917. Walter died 30 Jun 1951 and Beatrice was named as executor of his estate. At the time of Walter's death they were living at 24 Corfe Ave South Harrow. Election registration for Walter and Beatrice in 1950 show this address to in the Roxeth Ward of Harrow West. There is a 1959 registration for a Beatrice Newman living at 33 Wyvenhoe Rd in the Roxeth Ward but I have no idea if she is mine.

Edit-Forgot to mention that daughter Joan and husband Arthur Underwood moved to Australia and died in Moreland City,Victoria.
