Each has his own tree of ancestors, but at the top of all sits Probably Arboreal.

He is not easy to describe. There is something wrong with his appearance; something displeasing, something downright detestable. I never saw a man I so disliked, and yet I scarce know why. He must be deformed somewhere; he gives a strong feeling of deformity, although I couldn’t specify the point. He’s an extraordinary-looking man, and yet I really can name nothing out of the way. No sir; I can make no hand of it; I can’t describe him. And it’s not want of memory; for I declare I can see him this moment.

The mark of a Scot of all classes [is that] he ... remembers and cherishes the memory of his forebears, good or bad; and there burns alive in him a sense of identity with the dead even to the twentieth generation.

I've a grand memory for forgetting.
