Wittelsbach asked me to look up Ludwig III (Duke of Bavaria), so I did -- and nothing came up. I found Ludwig III, King of Bavaria, but no duke. Puzzled, I eventually checked for Ludwig II (1229-1294), which came right up -- father of Ludwig IV, Holy Roman Emperor--per wikipedia at https://en.wikipedia.org/wiki/Louis_II,_Duke_of_Bavaria -- with no Ludwig III. Wikipedia also shows that Ludwig II had an elder son Ludwig by an earlier wife (1267-1290), who was killed in a tournament before his father's death. Wikipedia page for Ludwig II: https://en.wikipedia.org/wiki/Louis_II,_Duke_of_Bavaria
Emperor Ludwig IV explains: "Ludwig III was killed. Ludwig had the sight. Ludwig and his father knew that the sight had to be concealed. Ludwig had the ability to tell people how to act, and this drew suspicion. Ludwig wanted to be able to be popular. Ludwig ignored the advice of his father."
Earlier in the Wittelsbach lineage is Otto II, Count of Scheyern, who is not in the main line of descent. The ancestors say that Otto had a natural son, who had a daughter: "The daughter of Otto's son married into a noble family that was well-known but not of the highest rank." The ancestors further said that the husband of the daughter of Otto's son was in the line of Habsburg, "before Habsburg became Habsburg." I looked around wikipedia and identified Albert III, whose wife was Ida, daughter of Count Rudolf of Pfullendorf (and, per the ancestors, son of a natural son of Otto II, Count of Scheyern).
As an aside, the Wittelsbachs were anti-Nazi during World War II, and they paid for it.
Oldenburg (the house of the Kings of Denmark) told me that the male line of the family that is currently on the throne of Denmark is indeed descended. Prince Charles and Prince Philip of England are allegedly descended from Oldenburg, but Oldenburg says this is not the case. As I went through the lineage, Oldenburg said that the line failed at Christian III, King of Denmark, the alleged father of younger son John, Duke of Schleswig-Holstein-Sonderburg. According to King Christian: "Christian was not the father of John. Christian did not want more children, but his wife did, so Christian acquiesced."
According to Savoy, "Philibert, the current head of the House, is descended from Philibert, Duke of Savoy."
