List of Famous people with last name Loon

Agnes of Loon (1150–1191), was a duchess consort of Bavaria, married to Otto I of Wittelsbach, Duke of Bavaria. She was regent of Bavaria during the minority of her son, Louis I, Duke of Bavaria, from 1183 to 1191. She was the daughter of Louis I, Count of Loon, and Agnes of Metz. Agnes was described as a forceful regent, who managed to secure the inheritance of her son.

Count Gerard of Loon, was son and successor of Louis I, Count of Loon, and Agnes of Metz. He was count of Loon and of Rieneck. Because of a widespread misunderstanding concerning a document from 1101, some generations earlier, he is sometimes wrongly referred to as the second Gerard in this dynasty, "Gerard II".

Louis was the Count of Loon, now in modern Belgium, Burgrave of Mainz, in Germany. He inherited these offices from his father. He also established the County of Rieneck apparently based upon the Burgrave's lands.

Arnold III, Count of Looz and Count of Rieneck, son of Gérard II, Count of Looz, and Adelaide of Gelderland, daughter of Henry I, Count of Guelders, and Agnes of Arnstein, daughter of Louis III of Arnstein.

Louis II was count of Loon between the end of the 12th century to 1218. He was the son of Gerard, Count of Looz, and Adelaide of Gelderland, daughter of Henry I, Count of Guelders, and Agnes of Arnstein, daughter of Louis III of Arnstein. He also claimed to be the legitimate Count of Holland during the Loon War (1203–1206).

Giselbert van Loon is probably the first, or in any case the first definitely known count of the County of Loon, a territory which, at least in later times, roughly corresponded to the modern Belgian province of Limburg, and generations later became a lordship directly under the Prince-bishopric of Liège. Very little is known about him except that he had two brothers, one of whom, Bishop Balderic II of Liège, is much better attested in historical records.

Henry, Count of Looz and Count of Duras, son of Gérard II, Count of Looz, and Adelaide of Gelderland, daughter of Henry I, Count of Guelders, and Agnes of Arnstein, daughter of Louis III of Arnstein.
