A plaque like the one proposed is an excellent idea.
Following on from my earlier reply regarding Tpr. C.J. Walkling, the Oz-Boer database identifies several members of 3NSWMR who came from Uralla NSW or close by. They are:
Tpr. John Alexander McCrossin
Tpr. William McHugh
Tpr. Percival Claude Williamson
Tpr. George Cuthbert Francis (actually he was from Emmaville, but NoK in Uralla).
There could have been several others from your general area who served in either of the Bushmen's contingents or in 1st/2nd NSWMR - or even the Aust. Comm. Horse. The best way to follow up is to look on TROVE for any such references in copies of the Armidale Chronicle or any local papers. There are frequently group photographs of members of the NSW contingents on TROVE: The Australian Town and Country Journal for example. Unfortunately, the images are often muddy and unclear. Caused by the passage of time and newsprint quality of the day.
Good luck with your quest. If the local RSL sub-branch succeeds in the placement of the plaque, you might care to post a pic on this site.
