Thank you all for the replies so far.
The birth date was 1859, but I believe that may have been an approximate. As an adult, Edwin Pitt and his wife had 12 children between 1886 and 1908 (8 sons and 4 daughters). His wife was Sarah Elizabeth Holmes, who was born in New Zealand (her parents were John Holmes and Harriet Anne Baker). He died on the 13th of April 1922 in Christchurch, New Zealand. I have no information on when he left England.
