Have you checked using the names or variations that are on her marriage registration?
STODART ROBERT m. LYNE HELENA 1869 QUEANBEYAN #3339
Thanks Merlin stumbled across this late last night will have to apply for it so hopefuly it will give more clues.
Thanks for looking. I have no details regarding the parents perhaps there is a transcript error somewhere.
