I came across this on Youtube. It’s a three-part video compilation explaining the origins of each of the families from the show. They are voiced by the actual actors and make for fascinating viewing, particularly if you haven’t read the books.
This is part 3a, and runs for little under an hour. Part 3 comes in two parts because of the running time.
