The Keyserlings burned down a lot of Cuthbert, damaged the organ, kidnapped Margaret Shabbleman and stole the Libra Personae at some point during the childhood of Florence Shabbleman. I believe after that, the Keyserling family died out, and the Libra somehow ended up in possession of Margaret Shabbleman, though I do not believe how she came to posess the book or what happened to the Keyserling family was ever written down. Your line in TWS where will discovers the hidden Keyserling lab explicitly says that Will only managed to decode some of the journals of the founder of the Keyserling University, not those of his descendants who might have explained that.
