We have discovered that Captain John married Anne Willcox on the 12th October 1858 in the St Barnabas Church in Auckland. We had initially dismissed that date as Anne was so young, she was 17 years old. He is listed as 28 on the marriage certificate but was actually 36. He is also listed as a "widower". The marriage seems to have been a happy one and they had 9 children, 5 boys, and 4 girls (more than we first thought). When Anne died in 1923 her death notice read:
On April 28th at her daughter's residence, no.10 Baker Street. Anne, the dearly beloved wife of the late Captain John Austen, aged 81 years. Deeply regretted.
