Hopefully I am not going off on a tangent or duplicating other posts on those other threads.
Maria (Minnie) WONNOCOTT, wife and mother, perhaps was born Maria MINTON, to Thomas and Mary.
Maria’s sister, Bella SHEPHERD memorialised Maria in the SMH of 10 March 1917 on the one year anniversary. So, if from my armchair searchings this morning, IF Maria was born Maria MINTON, then Bella was also their daughter too.
http://trove.nla.gov.au/ndp/del/article/15718101 So, from the online index, Maria Wonnocott’s 1916 death shows her parents as Thomas and Mary. The informant seems to know both Maria’s parents names, so Mary was not forgotten, and I suspect that Maria was the lass born in 1872 at Hotham, and that Bella was the lass born in 1874 at Collingwood.
From either of their marriage certificates, perhaps it can be determined if Mary was still living at those times, (perhaps not noted as deceased), or even perhaps if Mary had changed her surname (so, perhaps not just her maiden name, but her then surname, eg Mary XXXXX, formerly MINTON, nee MURPHY) …. Not all NSW BDM marriage registrations went to that level of detail, so perhaps these two mcs can be on a WISH LIST rather than on a MUST GET list. And of course, full official transcrptions are the better option as they have the details without the more expensive real deal certificate.
Maria’s NSW BDM seems to be registered in 1895, #4477, twice indexed perhaps due to difficulty reading her husband’s surname (WONNOCOLL and WONNOCOTT) and Bella’s is also twice indexed, but in 1893. #1075 (Arabella G and Isabella G). These two marriages were in Sydney. So, hopefully both have been fully reconciled by NSW BDM with their respective Church Records. Bella would not have been 21 years, so likely would have needed a parent to provide consent, and their name and relationship should be on the mc transcription.
Here’s the link to the many notices for Maria’s funeral, so many different family names, and friends too.

Fingers crossed there’s someone who has already researched and has joined the dots and has Mary’s information available to share, but it seems to me that Mary was known to her daughters regardless of their admission by their Dad in their childhood to Randwick Asylum for Destitute Children, and their subsequent discharge (along with two brothers) in March 1878 to their Dad, Thomas Minton, of Kent Street, Sydney.

That seems to have exhausted my resources, sorry.

oops. Sands 1900. Henry WONNOCOTT, 64 Macquarie Street, South (JM notes this is almost into what could be considered today as Surry Hills, it is to the south side of Liverpool Street Sydney, near to Commonwealth St ..... which in turn was formerly known as Little Macquarie Street South)
