The following year, the marriage was arranged at Siegen with a messenger from Walburga's father.

[11] Shortly before, on 16 February 1506, the Beilager of William's sisters Elisabeth and Mary, who married the counts John III of Wied [de] and Jobst I of Holstein-Schauenburg-Pinneberg respectively, was celebrated in Dillenburg with the greatest of festivities.

[14] Walburga died on 7 March 1529[1][2][3][15] and was buried next to her eldest daughter in the crypt of St. John's Church in the Franciscan monastery in Siegen, which her father-in-law had founded.

[16] William's brother Henry suggested the widower to look for a new life companion in the highest princely houses and suggested a princess of Lorraine, "die ein gut heiratgut mitbrächte" ("who brought in a rich marital estate").

[12] Instead William remarried in Siegen on 20 September 1531[1][2][3][15][17][18] to Countess Juliane of Stolberg-Wernigerode (Stolberg, 15 February 1506[1][2][3][5][17] – Dillenburg, 18 June 1580[1][2][3][5][15][17]).
