I think many of us, when we discover slave owners, or Slave Ship Captains, in our ancestry, feel rather uncomfortable, to say the least.
Most of us have, even if we didn't start off with a good grasp of History, gained a great deal more of knowledge of world history as our researching develops.
I've always regarded a good education, wherever it is gained, as being more about knowing, or being able to work out where to find information, than having a sort of haversack of facts concealed about one's person, learned in youth and unmodified in later life! Surely one learns some new thing each day - and many of us say / do something totally unintentionally that pops us into an awkward situation from time to time. If anyone's education stopped the day they left University, that would be so sad.
I've recorded this episode, and am really looking forward to watching it. All I knew of the woman previously was the impression from a few chance sightings of programmes of a rather "talking down" popular science presenter, who I always felt was aiming at the "Yoof" market. It sounds as if she has a far richer hinterland than that.
