Hi Beverly:
My (our?) cousins, Susan and Marty Powell have published quite a list of the
English/Canadian/American/Australian Chaffey clan and you can download a PDF of their book
at
http://home.earthlink.net/~mcpowell5757/index.html if you have any question after
you have perused their tome perhaps they can put you in contact with another Australian
researcher, you can always ask me, but I do not know much about the Austrailian branch,
still I will help if I can.
Mike
