Harriet Grace Champion was aged 25 when she married George Glover, aged 24 on 6 Nov 1839. (family search Historic Records I07586-9 ) and as mentioned earlier, this seems to be a Presbyterian service.
Again as mentioned earlier, it is likely that she died in 1909, if so, then it is likely her death was registered at Petersham, NSW with parents GIVEN names recorded at NSW BDM as George and Susan. #10755.
As Bertha was still living at that time, I wonder if Bertha was the informant, or at least helped the informant with the names of Harriet's children, as it seems to me that with Bertha being the eldest then it would be likely she knew which of her siblings belonged to each of the two likely wives of George Glover.
