"Comes Arnulfus de Los et filius eius Arnolfus" witnessed a charter of Adalbéron Bishop of Liège dated 1125.

Comte de Looz.... Daris suggests that there were two comtes de Looz named Arnaud, basing his argument on chronology which appears to be cogent. "…Comitis Arnulfi [comte de Looz], Arnulfi de Arescloth…" witnessed the charter dated 1131, before 18 Mar, under which Alexander Bishop of Liège donated property to Flône. "…Arnoldus Moguntinus comes…" witnessed the charter dated 1132, after 13 Sep, under which Adalbert Archbishop of Mainz donated property "in pago…Weitereibia…in comitatu Sigefridi comitis de Nuringes" to Mainz cathedral. under which Adalbert Archbishop of Mainz donated property "in pago…Weitereibia…in comitatu Sigefridi comitis de Nuringes" to Mainz cathedral. "Arnoldus…comes de Los cum Lodovico filio meo" founded Averboden abbey by charter dated 1135. Alexander Bishop of Liège confirmed the foundation of Averboden abbey by "comes Ernulfus de Los assensu…Ernulfi de Arscot, Ernulfi de Dist, Cunonis de Repe…" by undated charter, dated to [1136]. "Arnoldus…comes de Los cum Lodovico filio meo" donated property to Averboden abbey, which they had founded, by undated charter, dated to [1136]. Alexander Bishop of Liège confirmed the foundation of Averboden abbey by "comes Ernulfus de Los", with the consent of "Ernulfi de Arscot, Ernulfi de Dist, Cunonis de Repe", by undated charter, dated to [1136]. "Comes de Claromonte Lambertus" granted the right to take wood from his forests in "predicti castelli" to the monks of Flône by charter dated 1136, witnessed by "comes Arnulfus de Los, comes Gislebertus de Duras, Walterus advocatus de Barz…".

Married Aleide, daughter of ---. Her marriage is confirmed by the spurious charter dated 23 Jun 1180 under which her supposed grandson "Robertus de Ghoer miles, dominus in Bierlos et Castri Stephani in Corswarem" donated revenue from property which supplemented the donation made by "Arnoldo comite de Los et Aleide avis meis", for the souls of "patris mei Johannis de Los domini de Ghoer…". Borman suggests that this charter, whose authenticity was first doubted in 1808, was written in [1720] in an attempt to convince the Corswarem family of their alleged descent from the comtes de Looz. While the existence of her alleged son and grandson Jean and Robert cannot be verified by other sources, it is possible that the forger of the document used the correct name of the wife of Arnaud [II] Comte de Looz to support the authenticity of his production. No primary source has yet been identified which confirms that this speculation is correct. ¹
