DEATH OF ANOTHER OLD SETTLER - It is our painful duty to record the death of another of the oldest settlers, and one who has always been held in the highest esteem. Mrs Dodson Senr., the wife of Mr Thomas Dodson, of Wakapuaka, arrived in Nelson in 1842, being a passenger, we believe, in the first ship following the expedition ships, and after residing in the district for 42 years, she has departed this life at the age of 71 years, honored and respected by all. The deceased lady was twice married, her first husband, Mr Northam, having been at the Wairau Massacre, she leaves a large number of descendants. The funeral is to take place on Thursday, and will, we are certain, be attended by a very large number of settlers.

Brian of nzolivers.com notes,“Mrs Dodson Senr., the wife of Mr Thomas Dodson”, came out on the ship ‘Sir Charles Forbes’, arriving in Nelson on 22 August 1842. She was married to William Northam and was registered as ’Elizabeth Northam’ on the passenger list. Her and husband William came out with their two children, Mary Ann Northam and William Northam.
Elizabeth’s second husband, Thomas Dodson had arrived earlier in Nelson on the ship “Will Watch” on 4 November 1841.
