Had a quick look at the fiche for Parish Registers, Canberra and Goulburn Anglican Diocese, which includes Braidwood and Araluen.
There was very little extra we can add so I assume they may have belonged to a different church, or weren't baptised, buried etc in the Anglican ministry. Here's what I found:
Annie Elizabeth VERNES, baptised 12 April 1863 at Braidwood.
Aaron ANSON, the elder one who arrived first in 1841 with his wife Elizabeth.
Both buried at Braidwood - Aaron 30 July 1882, Elizabeth 19 September 1888.
