My grandfather was Eli Hartig , youngest son of Franz who lived in Cloncurry. Wife of Eli was Mona Hill. My mother Evelyn Hartig who married George eldest son of Eli has a lot of information on the family. I too would like to find out more about what transpired in Maree and Hergott Springs. The story we have is that the family started to take their team to Queensland( gunpowder ) in response to mining and there was a death on the way. I can give you Mums contact but reluctant to over the net. I will send her this link and maybe she can feed into it. I think Charles Richardon was one of my fathers friends.
