There's always been Hallowe'en in my family, and where I was at school on the Wirral. It meant doing fun things with apples with your hands tied up – ducking for them in a bowl of water with a fork held in your mouth, or bobbing for them as they dangle from a string. Oh, and turnip lanterns, which were smaller and harder work than pumpkins but somehow more satisfying. There was a Canadian family nearby and I remember going there for Hallowe'en and making taffy, a north American confection that involves stretching a sugar and glyceribe mixture over and over (so a bit like seaside rock only not hard. I enjoyed that, you got the sweeties in the end but you had to work hard for them.
In Scotland the tradition of guising at Samhain remains – children dress up (using imagination and materials found around the home, not mass-produced plastic in orange and black) – and went from house/farm to house/farm looking for goodies – not necessarily big-name sweeties but tablet, cake or fruit. That tradition goes back much further than American trick or treat; Scotland never let it go and England is just reimporting it – restoring to its original date the tradition that had been shifted for political reasons to 5 November.
There were fires at Samhain too, I understand, but not from any love for James VII and for a lot longer. Samhain, Hallowe'en and Bonfire night are the same thing really; a harvest festival.
