Thomas Hansen's father, Captain Thomas Hansen, skippered the ship Active, which brought the Rev Marsden's missionary contingent of European settlers from New South Wales to the Bay of Islands in 1814.
Young Thomas remained with the new settlement and, after returning briefly to Sydney to find a wife, was married by Marsden to Elizabeth Tollis, 17, on Christmas Day 1815.
Captain Thomas Hansen's daughter Hannah married missionary John King. They were the only missionary family to live the rest of their lives in New Zealand.
Descendants of Thomas and Elizabeth Hansen's 11 children include some well-known identities such as former Miss Universe 1983 Lorraine Downes.
Family historian Kath Hansen has published considerable information about the beginnings of the family in a series of small booklets.
