Dodgy ancestors?

I decided to have a day trying to learn some facts that may come up at this mystery exam that we are still awaiting a mock exam paper to see what it might include... 
So the question of what to blip was the elephant in the room. Ah idea! Have a look if the book of Guernsey people has any snippets I could use so I checked out my name. Mmm not the highest pillars of Guernsey society it appears; whichever way you spell it.
