Oh hey they actually named Thüringen as her homeland. So her family name of Von Wattin is actually a barely changed version of the actual Royal Dynastic House Von Wettin which actually ruled much of that area.
Fun Fact; The House Von Wettin actually still exists not only in its direct form, but also in its most famous Cadet Branch, the House von Saxe-Coburg and Gotha, better known nowadays as the House of Windsor or The British Royal Family. I don't think this story has given us a proper time frame, but I would guess this is mid 19th Century-Ish, possibly just turned 1900. So she might have relatives ruling (through marriage) the World Superpower in a few years. Sadly this would mean her family has Lost the Ownership of their version of Poland.
