Hi Ann,
your post was a very long time ago now but I thought I would reply anyway. My maiden name was Sharon Poke and I am from the Poke clan that Peter referred to in his reply, originally from Circular Head in Tasmania. We are descended from Ann (nee Siggs) and John Poke who departed from Sussex in the mid 1800's and subsequently settled in the Circular Head area.
Although I now live in NSW, my family and the many branches still populate this area of Tasmania.
I have tried many times to trace John and Ann prior to their arrival in Australia without much success so far. I would be very interested whether these are the same people you were referring to because I believe they sailed out on the 'Rapid' as well.
You are welcome to email me at
