William and Mary Ann weren’t the first Sanders to arrive in Australia another member of the family Thomas Sanders a convict arrived 1-8-1791 with the 3rd Fleet on the Matilda born 16-8-1766 died 3-9-1846 buried St Johns Cemetery Parramatta he owned a property at Prospect. Thomas was the brother of William born 1770 who married Sarah Stark 8-10-1790. I’d say this is the property William and Mary Ann stayed when they first arrived and their first child Elizabeth was born before they went north.
