Regintrud (also Reginlind and Regentrud), (b. 660665 Note: this provided date of birth would be invalid if she is Dagobert I's daughter as he died 639) d. 730740) is something of an enigma. The sources quoted by Schreibner indicate that the records show a Regentrud as the sister of Adela of Pfalzel and daughter of king Dagobert I. This is supported by the following:
Another Regentrud being listed in the tradition book of the Nonnberg Abbey as regentrudis regina (marking her a Merovingian princess)
The names of her sons, through her marriage to duke Theodo of Bavaria, are also Merovingian, that is, from the families of Regentrud and Adela
According to these sources, 8th century witnesses only mention Folchaid as the wife of Theodo. The supposition that queen Regintrud, the benefactor of the abbey founded by Rupert of Salzburg and Theodo mentioned above, must therefore be the wife of Theodo, is attributed to the 15th century historians Suntheim and Aventin. As an alternative explanation, the sources suggest that Regintrud was the queen of Theudebert, who may have had his support of the abbey attributed instead to his late father, Theodo. After the death of Theudebert, another Regentrud entered the Nonnberg Abbey and later became abbess in 720-725. This is listed in the Salzburger Verbrüderungsbuch in 784. Assuming the abbess Regentrud and queen Regentrud are the same, she may have entered the abbey on her husbands death. This could explain why the name of Theudeberts wife is excluded in the communion book of St. Peter in respect for her position as abbess. However, much of this is mere speculation based on the individuals named being the same.
The following lineages have been suggested:
Daughter of the Seneschal (and Pfalzgraf) Hugobert and Irmina of Oeren.
Daughter of Dagobert I
Daughter of Childebert III
She is married to Theudebert van Beieren.
They got married.
