Alistair and my Grandfather George were first cousins. I'm not sure how I relate to Alistair...

You are Alistair's first cousin, twice removed. Your great grandfather/mother and Alistair's father/mother were siblings, so your great,great grandparents were Alistair's grandparents.

Grandfather = first cousin
Father = 1st cousin, once removed
You = 1st cousin, twice removed.
