In a paper on the nuns compelled to enter monastic life in the Venetian Republic, published in the Sixteenth Century Journal, Anne Jacobson Schutte cited, among others, the case of the Zadar nun Cattarina Marchi. Zadar archival sources offer new insights about the Zadar nun, provide answers to the questions posed by Schutte and shed new light on Marchi's petition for the annulment of monastic vows. The analysis and synthesis of archival sources in Zadar, as well as other archival sources, have changed the entire narrative surrounding the nun Marchi, justifying the doubt about the authenticity of the story (true story) regarding her forced entry into the monastery. It will be shown that her case must be considered in the context of economic, social and religious relations between the Zadar nobility and its middle class in the 16th-18th century, especially from the point of view of inalienable inheritance rights, known as fedecommesso. U radu koji je Anne Jacobson Schutte objavila u časopisu Sixteenth Century Journal o časnim sestrama koje su u Mletačkoj Republici prisiljavali na redovnički život, navodi se, između ostalih, slučaj zadarske opatice Cattarine Marchi. Zadarski arhivski izvori donose nove spoznaje o tom slučaju, daju odgovore na pitanja koja je postavila Jacobson Schutte i bacaju novo svjetlo na zamolbu redovnice Marchi da joj se poništi redovnički zavjet. Analiza i sinteza arhivskih izvora u Zadru, kao i drugih arhivskih izvora, promijenili su cijeli narativ oko časne sestre Marchi, opravdavajući sumnju u autentičnost priče (istinite priče) o njezinu prisilnom odlasku u samostan. Pokazat će se da njezin slučaj treba promatrati u kontekstu gospodarskih, društvenih i vjerskih odnosa zadarskog plemstva i građanstva u razdoblju od 16. do 18. stoljeća, posebice s obzirom na neotuđiva nasljedna prava, poznata kao fedecommesso.
