I am a deaf historian of New Zealand and I was looking for a link of Dorcas Mitchell via Steve Hooker's presentation the other days. Steve Hooker passed away this year. However, I would like some information about your great great aunt from you. Perhaps photos if you have got one and any other information about her.. I understand and believe that Dorcas travelled to Napier from Gravesend, London when she applied for the job in Napier and moved on to Christchurch where she taught the Bradleys family who had deaf children. I understand that she was taught to become a teacher in London before moving here until I read your article that she was taught in Rockangle along with her sister. That is really interesting. I am doing researching in the Deaf History for the community and starting writing a book... Your great great aunt was the first teacher to take up teaching deaf children before Van Asch and the government. I can be contact by email at jemdeafhistory45@icloud.com Thank you and i hope to receive any email from you.... Lovely blog about Christian and I am a christian person.
