The Fine & Appel Families of Australia

For years now I have been trying to increase the branches of our family trees history. It is a never ending struggle to fill in all the missing information. The Second World War took most of our family and thus making it very difficult to find all the missing pieces to the puzzle. I guess there has to be a starting point where all the information is accurate and up-to-date to make future entries flawless.
I am always looking for new members of the Wartski and Appel families, as my grandparents on both sides were very young during the war and do not have the memory for distant relatives at the time.
But any information about any links to people on my family tree is always appreciated.
