Can anyone provide information on Silas Hunter Harding "Dairyman" or Charles James Harding "Grazier" both of Yahmahnto Queensland?

I am endeavouring to establish if either of them shared farmed or leased part of their property to share farmers or employed other farmers from 1908 until 1935.

My research interest is George Rider/Ryder who was a farmer at Yahmahnto during this time and it has been suggested he was with "Ty" Harding my thoughts are that this may have been a nickname or could have been "Si" short for Silas.

Any information appreciated.
