Man I fail at christmas... could anyone help me with present suggestions for my family?

I’m not really close to my family so I don’t really have that much clue what they actually want. So what I would love is some neutral suggestions for gift ideas.

My mum and younger sister – smellies and scarfs
Brother – don’t really want to get him a game again
Dad – no clue here but maybe could decide if he would like a suggestion
Nan – likes chocolates, biscuits, and sitting down watching tv all day :p

Gogogo. Lurve for the best responses that I will consider.
