Hello fellow seekers of information
I’ve been doing my family tree but wow have I hit a brick wall on my dad’s paternal side of the Miller family . I’ve got back to the 1600’s on my nans side of the family and both sides of my mums family I’ve traced that all the way back to the early 1600s. But the Millers 

all ive got is dad Darryl John (b1948
pop William Edward (death 1998 ) he had an older brother who died before he was born Harry John 1919 to 1922.
Great pop Micheal john 1889 to 1949 and.
Gg pop Harry Miller i dont have any information except his wife’s name was Mary.
Not sure but I’m starting to think harry or mary or both may be Aboriginal as there are no records but could be wrong any help would be greatly appreciated
Probably this one?
Michael John Miller was born in Hindmarsh, SA on 24 Sep 1887. He was the son of Henry Miller and Mary McIner(he)ney (Her surname is spelled in various formats).
On 26 Feb 1878 Henry Edward (24y) and Mary (22y) were married in Gum Flat, SA (Gum Flat was the original European name for the township of Minlaton on the Yorke Peninsula). They would have one daughter in Minlaton, but after this they could be found in the Hindmarsh district.
Henry’s father was John Miller and Mary’s was Michael McInerheney. They would have abt 10 children (one died in 1880, 4 weeks old)
This seems to be Mary’s 1941 obit: Making sure you're not a bot! . She’s 83 so born abt 1857/8 in Ireland.
Henry Edward Millers 1917 funeral notice: Making sure you're not a bot!
Also regarding Henry’s death: Making sure you're not a bot!
The couple are buried together in West Terrace Cemetery.
To confirm Michael John’s South Australian birth, you could buy his 1918 marriage certifiate and/or his 1949 death certificate …
Confirmation of Michael’s place of birth:
(Ie Brompton in the Hindmarsh area)
