Trying to trace my aboriginal ancester.

This rather confusing.

My aboriginal ancestory on my mothers side is causing me a lot of confusion with a lot of dead ends.

Aparently the story goes that my gg grandfather by the name of John Hawkins who lived in the Macdonald River area of the Hawkesbury in NSW, employed?? an aboriginal woman to care for his two daughters after his wife died.  Her name could of been either Margaret or Rose Lowe.  Anyway, from this union my great grandmother was born by the name of Margaret Hawkins.  However there is no birth record.  There is no death record for her mother yet she is listed on John Hawkins death certificate as his wife, no marriage record either.  My great grandmother married Edward Reilly of Webbs Creek in the Hawkesbury area in NSW, there is a marrage certificate with very little detail.  I realise this is a shot in the dark, but maybe someone may have heard of something.

Now it gets really confusing.  Her sister by the name of Frances Hawkins who married John Floyd, also in the Hawkesbury area of NSW, is listed as her mother in my great grandmother's hospital record???

On my grandmother's marriage certificate she lists her mother as Margaret Hawkins, but on her death certificate, her mother is listed as Margaret Floid.

If anyone is interested, I have more details and a photo of either my great grandmother or her mother??

I am not sure where to go with this confusing line of the family.

Here's hoping,

Trish
