In Who Do You Think You Are they are always saying things like that's why I love the sea when they find out they have ancestors who were sailors. How much do you think this could be true? I personally don't see it. I certainly hope not as quite frankly my father's ancestors were a load of drunken violent criminals. My father was a Methodist Clergyman. My husbands ancestors seem to have run a huge number of public bars and my husband is TeeTotall. He also had a lot of butchers in his family and 2 of his brothers are vegetarian.
