Thanks for that. However, a few things:
1. Packer (author of the article) is generally very good but with the excellent resources we have today, it's a lot easier and often more reliable to do research than it was in 1931.
2. Johnson and Sainty's book is incorrect. McKaeg died in 1851. The pre-1856 NSW church records show the accurate details.
3. New Zealand was never part of NSW, even in the early days. Victoria and Queensland appear in NSW records until their own dates of Separation, but never NZ.
