Ulrich I von Graben

Konrad I, Rennewart and Walther vom Graben can be seen as his (older) brothers.

[1] Ulrich had no parental inheritance,[2] joined like the Konradin line in the service of the powerful lords of Walsee and quickly made a large fortune there.

He and his descendants also had close ties to the Rein abbey of the Konradin line.

[3] He first appeared in 1302 as a feudal lord of the Stubenberg family (as the Konradin line did) when he received the village of Greindorf, south of Graz, as a fief from them.

[4] Ulrich was also the first burgrave of Gleichenberg, who held this office between 1302 and 1324 and probably also oversaw the construction of the castle.
