You have Eliza WHITE as marrying at age 18. From her marriage cert,

what was her usual place of residence,

who gave consent for her to marry, and what was their relationship to her

who were the witnesses

Is there any mention of WOTTON or variations on that document?

1869 Fanny WOOTTON death, with parents as Edward Bushe WOOTTON and Jane CROCKFORD #5557 and at Yarra, in 1868, birth #19715.
May I mention that there's an Eliza WHITE who arrived in Melbourne per Caduceus in 1870. She was aged 16, and a Teacher. She seems to have travelled with 18 year old Elizabeth A WHITE, also a Teacher.
It is on Elizabeth's record of passage that it states she was a domestic servant going to work for Mrs Wotton in Richmond.
Ah I see. So the assumption is that this is the same person who is mentioned in her obit as her aunt. Does it specifically mention Richmond? I am a little confused given the Sandridge link.
The surname WHITE was and still is quite a popular surname.
