“She was given the opportunity of life, and wanted to give that back to people,” said Nathan, who described her as a selfless, caring and very intelligent woman.
Diagnosed with cystic fibrosis at six weeks old, Ms Angell, from Fishguard, Pembrokeshire, her first transplant was when she was 17, when she had her liver replaced during her A-level studies.
This was followed by a transplant of her heart, lungs and later kidney, which was donated from her father David in 2006.
A person with unwavering resilience, David said despite being unable to move after their mutual surgeries, Allison was at his bedside less than 24 hours later.
“I couldn’t believe it, the following morning I heard a ‘tap tap tap’ and it was Allison, she had walked down to the corridor to my bed,” said David.
“Some people say the illness made her strong, but it didn’t, she was strong from the very start,” said Allison’s mother, Helen John.
