Bartolomea Artus, /!\

no trace of this profile in the link indicated:

-https://our-royal-titled-noble-and-commoner-ancestors.com/p4553.htm...

..& unfortunately the links on this site, regarding the Este family, do not match the official documentation studied in depth also recently by the historians Treccani

the site reports the threads from the respective marriages, completely ignoring all the illegitimate relationships, probably reporting the false historians proposed precisely for the popular legitimacy of the heirs. (not even necessary since there are papal bulls to legitimize them anyway)

• Obizzo III, marchese d'Este (OK, but the site reports the official wife, not the mother's lover of the natural child:)
  • Alberto V d'Este married Giovanna d'Este daughter of Cabrino de'Roberti, patrizio di Reggio Emilia [ ( with other confirmed family members around) (there is no evidence or even suspicion that he may be Roberto Marzano, 3°conte di Squillace , on the contrary the studies on the relatives adjacent to this last do not lead to the Este family)]
    • Niccolò III d'Este, marchese di Modena e Ferrara OK, but is natural son of Isotta Albaresani

however from the Treccani studies on the 3 adjacent profiles, the only similar surname appears from the page of her father in law, where a sister of her husband marries conte Carlo III d'Artus

..she is not even shown as wife in the husband diagram note:
-https://it.wikipedia.org/wiki/Marzano_(famiglia)#cite_note-19

..& not even known mother in the 2 encyclopedic pages of the 2 children.
