Allan's been mentioned in the Lamma-zine and this forum numerous times over the years, including being seen on the "Lamma My Island" video several times.
But this is my personal favourite, Lamma-zine Jul 7, 2006:
Allan telling me a story specifically for the Lamma-zine because he had heard that I was collecting tribute stories after our friend Pinky Chan's death:
'Pinky Enlightened Me!'
Allan had severed all contacts with all of his family in the UK, including his 3(?) sisters, a long time ago. His nephew found my story above online by pure chance, contacting me by email searching for his uncle Allan whom he had traveled with in Thailand and beyond. The story didn't mention Allan's surname, but the nephew thought, "that story sounds like uncle Allan!", and he was right.
I reconnected them, they talked on the phone and Allan got an update on his family and all their contacts. I'm not sure if Allan ever contacted his sisters as well, but at least they heard that he was still alive and living on Lamma. Thanks to this exchange, I had a contact to let his family know about Allan's death.
