In 1219, Ferdinand married Elisabeth of Hohenstaufen (1203–1235), daughter of the German king Philip of Swabia and Irene Angelina. Elisabeth was called Beatriz in Spain. Their children were:
Alfonso X, his successor
Eleanor (born 1227), died young
Berengaria (1228–1288/89), a nun at Las Huelgas
Philip (1231–1274). He was promised to the Church, but was so taken by the beauty of Christina of Norway, daughter of Haakon IV of Norway, who had been intended as a bride for one of his brothers, that he abandoned his holy vows and married her. She died in 1262, childless.
Sancho, Archbishop of Toledo and Seville (1233–1261)
John Manuel, Lord of Villena
Maria, died an infant in November 1235

Apparently, there were two Beatrix daughters of Philip, Beatrix the Elder and Beatrix the Younger
According to: https://www.britannica.com/biography/Otto-IV, Otto IV married Beatrix the Elder, who died three weeks after marriage. ("When Otto returned to Germany in March 1212, in order to retain the support of at least part of the Hohenstaufen faction, he married Philip’s daughter Beatrix, but he lost that support when she died within three weeks of their marriage").
The same source (https://www.britannica.com/biography/Philip-king-of-Germany) quotes that: " Eventually his daughters were married: Beatrix the Elder to his old rival Otto, Cunigunda to King Wenceslas of Bohemia, and Beatrix the Younger to Ferdinand III of Castile". Therefore, I believe that Otto IV has to be erased. Cordially
Of Swabia-65 and Hohenstaufen-2 appear to represent the same person because: It appears that someone created Of_Swabia-65 in error by using naming conventions other than those adopted by the Euro-Aristo projects. It is connected to many of the same primary family members of, & obviously represents the same woman as Hohenstaufen-2.
