I think I found the same link as the OP!
baz - can you scan and put up the backs, please.
I'm sorry Gadget, the scans were done about 10 years ago and the originals are in another city. They had nothing written on the back, otherwise, I would have noted the name in the name of the file
I suspect the first one is either the mother of, or Catherine Hodder herself (the only woman in that family that had a name written on the back of the picture). Catherine migrated to NZ in abt 1863/4
I can see a family resemblance I think between the 2 photos
Note that her head is covered and wearing a long ankle length dress. Not sure where her photo was taken, but presumably in NZ, as all her children were born in NZ
