She may have married Begon de Paris (c757-816).
Amaudru (c770) and three recorded children; and later generations Not mentioned by several researchers, including Medieval Lands. Some say she may be confused with a niece of Charlemagne (747-814) or another daughter. Medieval Lands lists a daughter (by an unnamed mistress "2") "CHROTHAIS [Rotaïde] (-after 800, maybe after 814)" then refers to her as "Ruodhaidem"; but despite the name and birth date similarity that site shows her as distinct from Madelgard's daughter. Reference to her mother on Die Genealogie der Franken und Frankreichs, noted by Wikipedia, says she later married a Count of Paris.
