Hi there,
Some "dating" clues for those photos !
The NSW State Library has a current digitisation project for the Holtermann Collection, (3,500 glass plate negatives ) and there's a blog.
http://blog.sl.nsw.gov.au/holtermann/index.cfm/2009/5/6/about-this-blogIt seems that the A & A company reached NSW from Victoria in 1870 .. on the blog, the curator for the digitisation project cites the Yass Courier of 18 Feb 1870, and also that Merlin left Bathurst late Dec 1872 for Orange, arriving Christmas 1872. Merlin's plans were to photograph all the colonial towns (see SMH Dec 13, 1872 page 5) .
Of course, as Hill End is North of Bathurst on the way to Gulgong/Mudgee, and as Orange is West of Bathurst and Merlin is associated with Gulgong and the photo used on the first ten dollar note for Australia issued 1966.... errr.... Moi
can't figure out exact Month that Merlin (the photographer) was at Hill End, but errrrr (excuse the pun) he was a Wizard photographer
Also, the photo with Mr and Mrs Ennis ... noticing the "flounce" at her hip. Could that be where her experienced Dressmaking skills allowed her to "take in" and "let out" for pregnancies ?
LB, I reckon once that digitisation project is completed, you will find more photos of her in that dress, perhaps with their teenage children
Oh well, back to searching for Elizabeth in around 1880 and later
Cheers, JM.
