You will notice the hume river mid map.  Humula?  Once called Amercian Yards if its anywhere near where some try and claim these days H and H went.  Sturt in his 1838 paper about the origin of the Hume River says Hume River is what we know today as Yanco Ck (he gives the co-ordinates) but he may have been referring to the Junction of Yanco Creek and the Murrumbidgee in which case the Hume River is likely the Murrumbeeja.
