Hi again Terry
Perhaps you've already seen the cemetery record at Linwood, Christchurch, for "an Edith Frances MAXWELL - d. 1955 aged 75 years" ? [Buried with James MAXWELL ].
The record shows she had lived in New Zealand for 65 years (arrived c. 1890) and was a native of Exmouth, England.
The passenger list index at "findmypast.org" shows an "Edith GOODWIN born 1880" travelling from Plymouth, England to Wellington in 1890. [Seems there are other family members with her?]
