I am sad to report that Doreen Brown passed away at North Shore Hospital in New Zealand on Wednesday 26 April 2023 after a short illness. There will be a memorial service held on the 27 May which will include a video link. If you would like the link or further details please send a message to Doreen's email or Facebook and I will be able to respond in a couple of weeks.
