In 1978 knowing nothing at that time about the First Fleet or William Tunks, Len Chalmers succumbed to pressure from some of his first cousins to compile a family tree of his grandparents’ descendants. In 1979 he was able to put together a family tree of William Henry Tunks and Charlotte Emily Harper and distributed a copy to the approximately 100 living descendants. During collection of information for this book he visited the Fellowship of First Fleet office and, happily, found four dedicated Tunks descendants working there. Joyce Cowell, her cousin Jean Cowell with sisters Hazel Liebau and Naida Jackson. Len and these four ladies assisted by others were the foundation on which the Tunks Descendants Association was built.
