Richeza Dithmarschen

"Richenza is certain that their mother was Ida von Elsdorf. According to Albert von Stade, Ida von Elsdorf was the niece of an emperor and a pope. However, the exact assignment is a riddle that has kept genealogists busy for more than 100 years. The same applies to the father of Richenza, since her mother was married three times. Her father Dedi or Dedo was probably not the Count of Dithmarschen, but the Saxon Palatine Count Dedi von Goseck, who was murdered in 1056. Richenza would then have been a niece of his brother Archbishop Adalbert of Bremen (1043-1072), which promoted the rise of her husband and her descendants."
