Hello Philip,

Philip said,
Averil, under your details of Thomas Joughin’s immigration arrival in 1875 you have put something about Probate records. Are they something that I should be looking at?

Averil said,
To be honest – I don’t know – maybe you should put on hold, until you can find a death date for, Thomas (James) Joughin.
Though it is FREE and will be time consuming.

There is only 1 Death in the N.Z. Historical BDMs.
This is for, Thomas Cannell Joughin in 1929
– searchable only up to the year 1929 – you can find later Deaths at the Papers Past website.
