She is married to Charles III "The Simple" King of France.
They got married about April 907 at 2nd wife.
Child(ren):
A number of people have Frederuna as the same person as Frederunda von Ringelheim, wife of Wichmann Billung (aka. Wickmann Count of Engern). I (note by Jim WEber - ed) think that Frederunda was born about 20 years later than Frederuna. Frederunda von Ringleheim's mother, Ragnhilde, was the daughter of an 882 marriage, which makes her birth date much too late to be the wife of Charles III and mother of Ermentrude.
