For Agatha's lineage see NEGHR, Vol. 106, p. 52-60. (C-437, p. 589) She was the niece of the Emperor Henry III. (C-685) She was also known as Agatha of Germany and Agatha of Hungary. However, it should be noted that her lineage is still in question and has other possibilities. She is sometimes listed as the daughter of Stephen, but this lineage is now thought to be incorrect. (C-870, 1351)
Agatha married Prince Edward "The Atheling"  [MRIN: 986], son of Edmund Ii Ironside, King Of England  and EALDGYTH , before 1045. (Prince Edward "The Atheling"  was born about 1016 and died in 1057 6.)
