Elected Bishop of Liège (Reichsfürst), Duc de Bouillon, Comte de Looz 21 Nov 1455, invested with the Principality of Liège 23 Oct 1473. He was murdered by Guillaume de la Marck "le Sanglier des Ardennes". Kerrebrouck discusses the claim that the mother of the children of Louis de Bourbon Bishop of Liège was Katharina van Egmont Regent of Geldern (1439-1496), first made in 1628 by the brothers Scévole and Louis de Saincte-Marthe, and embellished during the 18th century by the assertion of a secret marriage between the alleged couple[55]. Louis had three illegitimate children by an unknown mistress:
