Bertha, queen of Italy

- https://en.wikipedia.org/wiki/Bertha,_Queen_of_Italy - Her parentage is unknown, but:

• she is often said to be identical with Bertha of Milan,[1] who was a member of the Obertenghi dynasty. [Treccani & Medlands agree]
• Other scholars suggest that Bertha may have been the daughter of Hubert of Tuscany[2] or of Amadeus (son of Anscar II)[3]

There are 2 distinct pages also on wikipedia, which however report the probability, which we also find on her father's Wiki https://en.wikipedia.org/wiki/Otbert_II,_Margrave_of_Milan :

• half of the languages report the thesis of a single Berta. (the other half don't specify)
• MedLands simply quotes them in place 3) and 6) distinctly without specifications.

(it is certainly a beautiful coincidence that King Arduin is forced to abdicate and become a friar in exile in the mountains in 1013... and a sister of the same name from Berta is married in 1014... and Arduino dies in 1015... but what happened to the former Queen? :)

There is no document in MedLands that contradicts the thesis of a single Berta .. only the date of birth c.997 assigned to Berta(6) by whom or what? [and the "c." of MedLands are very elastic]
