The mother of Umm bint Uthman and Susu bint Uthman appears to be unknown but some sources say she was Lampade, said to be a daughter of Eudes, duke of Aquitaine and Adèle of Austrasia but she is not among their documented children. See MedLands.

This person seems fictitious:

Lampade was born about 0700 in Aquitaine (Ancien), the daughter of Eudes de Gascogne and Lampade d'Austrasie. Her husband was Uthman ibn Abu-Musá. They were married, but the date and place have not been found. Their only known child was NN (c0731-?).
