Hi Alan B,
I have had a good look through the family tree information in your web-site and we found it amazing - all the way back to the Norman Conquest of 1066! It must have been fascinating conducting the research.
I can't provide any more information on Henry Newick's life in Australia, apart from following his "path" through New South Wales by the birth locations of his children. But he appears to be an early pioneer in farming in the area around Parkes, NSW.
That' about it.
Cheers,
Mark
