-Henry I, Duke of Münsterberg-Oels (1448-98) and Margravine Ursula of Brandenburg (1450-1508) MRCA for Maurice, Landgrave of Hesse-Cassel and Countess Palatine Dorothea of the Rhine at Simmern: quadruple third cousins through four couples: - Magnus II, Duke of Mecklenburg (-Schwerin and Güstrow) (1441-1503) and Duchess Sophie of Pomerania (1460-1504) - Albert III, Elector of Brandenburg (1414-86) MRCA for Countess Juliane of Nassau-Siegen/ Dillenburg and Countess Palatine Dorothea of the Rhine at Simmern: 3rd cousins through: - Frederick I, Margrave of Brandenburg-Ansbach (1460-1536) and Sophia Jagiellon, Princess of Poland (1464-1512) Albert III, Elector of Brandenburg, is the father of two others mentioned here: Margravine Ursula and Margrave Frederick I. He is the common ancestor between John George I of Anhalt Dessau, Maurice of Hesse-Cassel, Dorothea of the Rhine/Palatinate, and Juliane of Nassau-Siegen/Dillenburg, but: I’d say your most recent common ancestors linking Portugal and Lippe to everyone else are Frederick I, Margrave of Brandenburg-Ansbach and Sophia Jagiellon, Princess of Poland. These two individuals are the most recent common ancestors between at least one half of each couple that link JWF to Lippe and JWF to Portugal, and are common ancestors between all of JWF’s descendants, the Prince of Lippe, and the Duke of Braganza.
