Sarah Evans was born in Greenwich, England.

Sarah Evans emigrated to New Zealand. It is not known if William Ellis accompanied her.

William Ellis appears on the electoral roll. It seems he was living in and operating a store of wood and iron, situated on the northern bank or the Kawarau River, near Cromwell.

William Ellis not listed in the New Zealand Directory for Bannockburn.

Mentioned in Mr J P Parcells notes - listed after Cairnmuir Station, heading downstream? "On river bank W Ellis, across the Kawarau Mr & Mrs Tom Graham."

Mentioned in Mr J P Parcells notes: Mr & Mrs W Ellis may well have lived in dwelling #126. It appears (from the will of W Ellis) that Sarah Evans had been living with William Ellis as his housekeeper for some time. It appears that the Bannockburn community were told, or presumed, that William and Sarah were married. She may have arrived c1866 with William Ellis.

On 23 Feb 1902, Mr Ellis died at the age of 72 years. He is buried in the Cromwell cemetery. In his will, William Ellis recorded that his estate was to be left "unto my housekeeper, Sarah Evans (generally known as Mrs Ellis)" The couple had no children. It appears that Sarah continued to live in dwelling #126 after Williams death.

On 27 Aug 1905 Mrs Sarah Evans died at the age of 74 years. She is buried in the Cromwell cemetery, as Mrs Sarah Ellis, with her 'husband' William Ellis. Her death certificate was issued in the name of Sarah Evans, never married, and stated that she died on the heart disease, dropsy.

On 16 Sep 1905, at 2pm sharp, Mrs Ellis's house (maybe dwelling #126) was auctioned along with its contents by Mr George Goodger of Cromwell. It was advertised in the Cromwell Argus on 11 Sep as: "residence area, about 1 acre, with three roomed house thereon. Also household furniture and effects including musical instruments, clocks, mirrors, tables, lamps, crcokery, chairs, tools and cooking utensils etc " It appears from Parcell's notes that Mr J R Crombie purchased dwelling #126.
