Biography

Oxenstierna was son of important nobles and landowners: his mother lady Märta Finvidsdotter was the heiress of the Frössvik high-noble family, and his father Jöns Bengtsson Oxenstierna was son and one of the heirs of lady Ingeborg Nilsdotter, heiress of Ängsö and Salsta. Jöns Bengtsson inherited Frössvik from his mother and Ängsö from his father. Oxenstierna is credited for having founded Djursholm Castle .
From his two earlier marriages, Oxenstierna did not succeed to have any surviving heirs. His third wife lady Karin of the Gumsehuvud-Sture family bore a number of children of whom half died without marriage and issue. His surviving son Erik did not have any children. Three of Oxenstierna's daughters married noblemen of the Vasa family, Oxenstierna's allies), but only through one of them, Kerstin who married lord Nils of Hjulsta, continues a more permanent issue. Due to such childlessness, a portion of Oxenstierna's properties passed ultimately to others than his own descendants, as inheritances through his daughters-in- and sons-in-law.
