Regintrud
Regintrud, also known as Reginlind and Regentrud, (born 660–665, died 730–740) probably was the wife of Duke Theudebert of Bavaria or of his father Duke Theodo of Bavaria. A possibly identical Regintrud became abbess of Nonnberg Abbey in 720–725. However, details about her ancestry and life are widely disputed among historians.
According to differing views, Regintrud was either a daughter of King Dagobert I, or of Pfalzgraf Hugobert and Irmina of Oeren, or of Childebert III.
