John II of Loon

  (Redirected from John II., of Loon-Heinsberg)

John II (Johann II), (d. 1438), Lord of Jülich, Heinsberg and Löwenberg (Herr zu Julich und Heinsberg), son of Godfrey de Heinsberg, Count of Looz, and Philippa of Jülich, daughter of William V, Duke of Jülich, and Joanna of Hainaut.

John married first Margaret (Margareta van Gennep, d. 1419), Countess of Solms-Braunfels, and second Anna of Solms (d. 1433). John and Margaret had four children:

  • Johann III (d. before 1441), married Walpurg von Mörs. Their granddaughter Johanna was the Countess of Nassau-Saarbrücken.
  • Wilhelm I (d. 24 April 1439), married Elizabeth von Blankenheim, daughter of Gerhard IX, Count of Blankenheim, great-great-grandson of Gerard I, Count of Durbuy.
  • John of Heinsberg (d. 1459), Bishop of Liège (1419-1455)
  • Philippa (d. 1464), married Wilhelm von Wied-Isenburg.

John and Anna had two children:

Among the descendants of John (through Maria of Loon-Heinsberg) were Juliane of Nassau-Dillenburg and William the Silent, Prince of Orange.
