documented evidence of this including ceremonial use, strengthens the integrity and rarity of the continuous physical record of the place. Important named historical Aboriginal figures such as Cannbaygal, a visiting chief from the mountains, are associated with the Denbigh farm, and possibly also Cogy (Cogrewoy) a leader of the "Cowpastures" Tribe who also acted as guide through the district to Macquarie and Barrallier.
