This may have been done, but I'm legitimately curious about Stephen I of the House of Blois winning the war in the era known as the Anarchy. I am curious as to how this might turn out. Ultimately, I have William, Count of Boulogne succeeding Stephen as William III. Would it be possible to create a timeline where Anglo-Norman culture persists till the modern day where English is a minority language using this as the POD? Let me know.
