She was the only child of Duke January IV of Oświęcim by his second wife Barbara, daughter of Duke Nicholas V of KarnióWest
Helena"s father lost his Duchy of Oświęcim in 1456 and the rest of his lands in 1482. In 1492 Helena married with Baron George of Schellenberg. One year later (in 1493), Helena"s parents were dispossessed from Karniów when the King Władysław II Jagiellon bestowed the Duchy to Baron Johann II, Helena"s father-in-law.
In 1523 Duke George sold Karniów with Głubczyce to George, Margrave of Brandenburg-Ansbach.
Helena probably died shortly afterwards.
