First thoughts of Charles George Penson heading for NZ about 1864/65 was possibly straitened family circumstances following death of Rev Penson. The Canfield living was worth about £90 a year and by 9 July 1864 a successor had been elected.
However, the '61 Census shows them living at Canfield and the household includes an 82 year old Elizabeth Penson, boarder, Fundholder. The 1892 will of Rev John's wife Catherine reveals her leaving "effects £14,622 3s 8d resworn Jul 1892, £8,883 6s 11d" - probate to dau. Maria and son Richard.
So, Charles travelling to NZ at around 17/18 years of age not necessarily driven by need?
