Many thanks Genni, I'm slowly getting my head around it.
Not only was John Broadhurst Boothman a part of the Port Phillip settlement and Hobart Town, but he got a ride on the "Lady Nelson" which (with the "Investigator" under the command of Matthew Flinders) explored much of the coastline of Australia.
There are so many discrepancies on the www. It seem that the Tasmanian Archives Web Site does not even have a listing for the Lady Nelson for 1804, the first being 1812. However it then lists them arriving on 1st ?? January 1804 aboard the "Calcutta" including John Broadhurst Boothman.
And Sue, I'm glad my John boothman did not go with William Buckley, otherwise I would not be here
