Seems the fact that William from the Barwell was around in the 1822 muster rules out the shopkeeper who returned to England in 1818.
There are at least three William Suttons.
- The convict who came out on the Neptune, Scarborough and Surprize, December 1789
- The convict who came out on the Barwell in 1795
- The shopkeeper who returned to England in 1819
The other key piece of information is:
I haven't found the evidence of the land grant, however this blog suggests that indeed the convict William SUTTON who arrived on the Barwell was given 148 acres of land in 1804.

This would tie in with this advertisement in Nov 1818 which says William SUTTON ("late of Sydney") left his land to his daughter Sarah WILKES.

So that could be seen as fairly strong confirmation that Sarah had a father called William who had land in the colony. If the land went to his daughter, why? He may have died but I cannot find a record. He may have left the colony. He may have been too old to unable to manage the land. Could this point to the first William who arrived in 1789? How accurate are immigration records of the time for convicts and free settlers?
Regarding the question of his birth as William Talbot Sutton in 1762, I found that reference on a number of family trees but have my doubts for two reasons. First the name Talbot does not appear again in any records I have found. Second, there is nothing to link the birth to any further events.
This post has turned up a lot of interesting facts, but I still cannot find a thread that ties them together.
