He held the titles as a Lord of Graben, Kornberg, the Lordship Marburg with Obermarburg and Maribor Castle, Radkersburg, Neudenstein, Weinberg and Burggrave (Viscount) of Saldenhofen.
This line owned the larger lordships of Kornberg and Marburg, Obermarburg (Maribor) among a lot of smaller fiefs in the Duchy of Styria.
He had two older brothers in Andree and Wilhelm, both his successor as Lords of Kornberg and Marburg and a cousin in Virgil von Graben, high official, governator of the County of Gorizia, as well as imperial governor and advisor of the Holy Roman Emperors Frederik III and Maximilian I. Wolfgang von Graben was first named in 1470 as heritage Jörg II Steinwalds of some manors of 30 styrian Stubenberg fiefs.
[5][6] According to another family tradition Wolfgang had another son, Abraham op den Graeff (around 1484-1561), from a marriage in Holland.
Returning to Austria around 1485, Wolfgang von Graben became one of the Holy Roman Emperor Friedrichs III major captains in the war against Matthias Corvinus.
[12] In the following year he succeeded his cousin Georg Breuner as lord of some smaller styrian and imperial fiefs.
[13] In 1494, Wolfgang and his two brothers Wilhelm and Andree negotiated with the Roman-German King Maximilian I about the estimated value of their share in the Glauning forest (municipality of Sankt Peter am Ottersbach), including villages, farmers and two ponds.
[22] Around 100 years and more later, during the Dutch Golden Age, the Amsterdam (de) Graeff family said that they descend from Wolfgang von Graben, who was in Holland between 1476 and 1483.
