At the time of her death, a joint statement from Pembrokeshire council and Ysgol Penrhyn Dewi said Honey was “much loved” and “cherished by all who knew her”.
“She was a keen performer and writer who gave generously of her humour, time and talents to support our school family and wider community – and she will be very much missed,” it said.
“Our love, thoughts and prayers go out to her family at this sad time.”
A fundraising page set up to support her family has raised thousands of pounds.
