Information from, “Family Tree: Cripps, Franklin, Brown”, dated December 1995, prepared by W J Darnell, Wellington, as per copy from Douglas and Kim (nee Jamieson) Cripps.

See wife Sarah’s person sheet for story on Isaac resigning as a policeman in 1849 and sailing in August of that year with Sarah and their three children in the ship ‘Fancy’ to the Auckland Islands, 465 kilometres south of Bluff, New Zealand.

The whaling and agricultural settlement township was called Hardwicke. Three ships in all sailed from England carrying sixty men, women and children, some livestock, and prefabricated buildings for the new settlement.
Their fourth child, Harriet, was born in 1851 on Auckland Island.
The flimsy cottages barely provided adequate shelter from the elements and the settlement collapsed in 1852. Most of the disillusioned settlers either shifted to Australia or returned to England. A few families, including Isaac and Sarah and children, moved to New Zealand. Sarah had been bedridden by seasickness on the four-and-a-half-month journey from England and refused to sail any further than necessary!

A book was written in 2018 by Shona Riddell of Wellington, great-great granddaughter of Harriet Cripps. Called, “Trial of Strength: Adventures and Misadventures on the Wild and Remote Subantarctic Islands” it is about New Zealand's subantarctic islands and their dramatic human history including that of her Cripps ancestors:
