Oxenstierna was son of important nobles and landowners: his mother Märta Finvidsdotter (Frössviksätten) was the heiress of the noble Frössvik family, and his father Jöns Bengtsson Oxenstierna (died 1396–99) was the son and one of the heirs of Ingeborg Nilsdotter (from family that is called the earliest Sparre in later historiography and genealogy), heiress of Ängsö and Salsta. Jöns Bengtsson inherited Frössvik (in Uppland) from his mother and Ängsö (in Västmanland) from his father. His brother, Bengt Jönsson Oxenstierna, was the father of Jöns Bengtsson (Oxenstierna), Archbishop of Uppsala (1417–1467). [3][4]

In 1418 he acquired an islet and the founded the estate Djursholm. There he built a manor house, later the site of Djursholm Castle (Djursholms slott) which dates from the 15th century but did not get its current appearance until the 17th century. [5]

From his two earlier marriages, Oxenstierna did not succeed to have any surviving male heir. His third wife Katarina Karlsdotter bore a number of children of whom half died without marriage and issue. His surviving son Erik Nilsson Oxenstierna (d. 1470) did not have any children. [6]

Three of Oxenstierna's daughters married noblemen of the Vasa family. Kerstin who married Nils of Hjulsta, continues a more permanent issue. A portion of Oxenstierna's properties passed ultimately to others than his direct descendants, as inheritances through his daughters-in- and sons-in-law.
