Hi there,
Do you have transcript or copy of the d.c. for her? I see it was registered at West Maitland, so there may be details in the Newcastle Herald.
Mary Louisa HAIN, parents given names indexed as Charles Willam and Bathsheeba # 24852
The NSW Coroner's Index shows inquest was 7 October 1936, and the cause was due to injuries from a car accident. She was aged 67, born Dunmore NSW, died Maitland District Hospital.
Cheers, JM
