Hi Everyone
Can anyone offer some suggestions

Ruth Irvine Baldwin, was born 13 July 1908 at Carlton, Vic to Henry Percy Baldwin & Euphemia, nee Irvine. She married twice, as Ivy Ruth Irvine Baldwin in 1931 to Arthur Alfred Frith and as Ruth Irvine Baldwin in 1943 to Francis Edward McRae, both marriages in Victoria. I cannot locate her on Electoral Rolls after 1937 as Ruth Irvine Frith. All other subjects with christian names of "Ruth Irvine" on accessible Australian Electoral Rolls have been discounted as the Ruth Baldwin I am tracking. Ancestry trees "suggest" she died in 1977, but this is likely to be speculation. I have tried locating a death record in Australia without success. As I cannot locate a Ruth Irvine McRae on records (as suggested by her 1943 marriage record) at all, I am wondering if the marriage failed early and she assumed a new identity.
She had a son Roland Kevin Newport (born 1928), variously known as Frith and Griffin. He is believed to have died circa 1990, the only record located on Electoral Rolls was in NSW in 1968, his chequered marital career is well documented on Trove. Again, like his mother, I am keen to determine possible dates & places of decease.
And before I outstay any welcome by asking way too much, Ruth's aunt Margaret Irvine (1880-1963) married Edward John Hammond in WA in 1901. Edward seems to disappear after 1916 when he was about 30 years of age. Margaret never remarried and died in Melbourne, they last appear together on an Electoral Roll in 1910. Any suggestions for Edward John Hammond?
Thank you all so much for reading.
Regards
Stuart McDonald
