Question: Who is Princess Elisabeth, Duchess In Bavaria's father-in-law?
Sentence (from "Prince Max, Duke in Bavaria"): He was born a Prince of Bavaria, as a member of the royal line of the House of Wittelsbach, but has been using the title "Herzog in Bayern" or Duke in Bavaria, since he was adopted as an adult by his great-uncle, Duke Ludwig Wilhelm in Bavaria, the last bearer of that title of a junior branch of the House of Wittelsbach, from whom he inherited considerable estates at Tegernsee Abbey (including a brewery), Banz Abbey and Kreuth.
Relevant evidence: No
