Lady Ingerd's parents had her marry Lord Nils Henriksson, whose family also had some claim to Austrått Manor in the Trondheimsfjord.
In 1528 the knight who claimed to be Nils Sture, the elder son of Sten Sture the Younger, the 1512–20 Regent of Sweden (the boy's identity remains controversial to this day: he may have been was the authentic Nils or an impostor), fled to Norway after his defeat and enjoyed the hospitality of Lady Ingerd.
[4] From earlier property disputes and such, Lady Ingerd was an enemy of the Roman Catholic prelate Olav Engelbrektsson, Primate of Norway and Archbishop of Nidaros.
Archbishop Engelbriktsonn was also a rival in Norway's government with Lady Ingerd's son-in-law Lord Vincens Lunge.
Ingerd Ottesdotter Rømer and Nils Henriksson had five daughters, all of whom married Danish-Norwegian noblemen: Lucie Nilsdatter had been the center of a social scandal of some substance in those times.
[11] In 1857, playwright Henrik Ibsen, then in his early career, wrote the play "Lady Inger of Ostrat" which loosely utilizes her intrigues towards Swedish throne as basis of drama.
