Betty Baxter

[sonyao]

Betty was born c1929 in Sydney, her mother was Rita Baxter nee Croker and father Roy Baxter.  Divorce proceedings were started in 1929. Roy denied Betty was his daughter but the daughter of the co-respondent William Robert Swindail, the spelling of his surname on the divorce documents given as Swindo and corrected to Swindale.
Roy died in 1952, Betty is included on his death certificate as one of his children, she was then aged 25 years.
The Baxter/Croker families lived in the inner Sydney suburbs of Balmain/Glebe/Leichhardt/Newton.  With that in mind I searched BDM and found a Betty Baxter marry Kenneth Frederick Julius in 1952 in  Newtown.
Betty and Kenneth appear on the Electoral Roll in Gilpin St Annandale in 1954 - 1958 then in 1968 Betty is not on the Electoral at that address only Kenneth and his mother Stella.  I have searched for Betty for such a long time without success.

Do you have Rita's 1988 death certificate to see if/how Betty is recorded, living or deceased?

cupoflife found Rita's probate grant refererence on your other post, it might also mention Betty as Rita outlived her last husband. 

Her sister Norma died in 2004 which unfortunately falls outside the easily accessible newspaper death notices but you can ask for a lookup.  If Betty was still alive she might be mentioned depending on the family dynamic at the time.
