Although Medlands and Wikipedia marry him to Agnes von Mainz, the daughter of Gerhard I, she would have been a generation younger and more likely married his son Arnold II. Other models have Arnold I married to a daughter of Folmar VI of Metz and his wife Suanehilde, possibly also named Swanhilde. Her existence is not proven.

Arnold I, Count of Loon

From Wikipedia, the free encyclopedia https://en.wikipedia.org/wiki/Arnold_I,_Count_of_Loon (April 2020)

Arnold I (approx 1050 - approx 1130), Count of Looz (Loon) (from approx 1079), son of Emmo, Count of Loon, and Suanhildis, daughter of Dirk III, Count of Holland, and his wife Othelandis.

He was an ally of Henry of Verdun and Otbert, both bishops of Liège. In 1078, he endowed the Collegiate Church of Huy and that of St. John at Liège.

In 1088, he spoke on the request of Bishop Henry of Verdun to end a conflict in the Abbey of St. Truiden where the bishop and emperor Henry IV had both appointed a successor abbot. As a result of his diplomacy, the emperor transferred the authority of the abbey of Sint-Truiden from Henry I, Duke of Lower Lorraine, to Arnold. Arnold forced Henry and his ally Godfrey of Bouillon, to withdraw from the monastery. The domain of Arnold expanded with the County of Rieneck by his marriage to Agnes.

Arnold married Agnes von Mainz, daughter of Gerhard I, Count of Rieneck, and Helwig von Bliescastel. Sources disagree on their number of children, but are believed to include:

• Gerard? (d. 1103, but probably did not exist). Count of Loon for a brief period according to the old Belgian National Biography, pointing to a charter of 1101. Baerten (1969 p.40 footnote 2) describes this as a mistake caused by modern edition with a wrongly placed comma, and gives references to the literature.
• Arnold II, Count of Looz. He is distinguished from his father of the same name by historians who note records for counts named Arnold or Arnulf between 1179 and 1141, which seems too long to be one person. The first Arnold must have died between 1125 when Count Arnold appears in a record with his son also named Arnold, and 1135, when a new Count Arnold appears with his own son and successor Louis.[1]
• Gertrude van Loon (1100-1154), married to Hugo XI, Count of Dagsburg. Their son was Hugo XII, Count of Dagsburg, who married Luitgarde, widow of Godfrey II, Count of Louvain. She was daughter of Berengar II of Sulzbach, and sister of Gertrude von Sulzbach, wife of Conrad III of Germany, and Bertha, wife of Manuel I Comnenus, the emperor of Byzantium. Their granddaughter was Gertrude of Dagsburg, wife of Theobald I, King of Navarre.
• Agnes van Loon (b. ca 1100), married Gerhard IV, Count of Jülich
• Beatrix van Loon (d. after 1132), married Arnout III, Count of Aarschot and had issue.

While the confusion about the non-existent "Gerard" remains, Arnold is now understood to have been succeeded by his son Arnold as Count of Looz upon his death.

ARNOUL Ier, fils d’Emmon, comte de Looz, commença son règne entre les années 1078 et 1082. En 1078, Emmon paraît encore, comme témoin, dans une charte par laquelle l’évêque Henri de Verdun fait des donations à la collégiale de Saint-Barthélémy de Liège; tandis que, en 1082, on voit figurer Arnoul parmi les principaux seigneurs du diocèse, que le même évêque avait convoqués pour fonder, avec leur concours, le célèbre Tribunal de Paix, destiné à mettre un terme à l’anarchie et aux guerres privées qui désolaient une grande partie du territoire actuel de la Belgique[1]. Six ans après, il joua un rôle important dans l’expédition entreprise pour étouffer les troubles suscités à Saint-Trond par les rivalités des moines Lantzon et Lupon, qui tous deux revendiquaient la prélature de la célèbre et riche abbaye seigneuriale de Saint-Trudon; le premier avait été nommé abbé par les évêques de Metz et de Liége, le second par l’empereur Henri IV[2]. La ville ayant pris le parti de Lupon, l’évêque de Liége, Henri de Verdun, vint l’assiéger à la demande de son collègue de Metz, copropriétaire de la seigneurie, et le comte de Looz l’accompagna avec un corps de troupes levé dans ses domaines. Ce fut à lui que Henri de Verdun, retournant à Liége après la reddition et l’incendie de la ville, confia la mission de s’emparer d’une grande tour, solidement bâtie à l’un des angles du monastère, où les religieux du parti de Lupon et une troupe de bourgeois armés avaient cherché un dernier refuge. Les assiégés ne tardèrent pas à se rendre; le riche trésor de l’abbaye fut pillé par les soldats, et Arnoul mit une garnison dans la tour, en attendant que le débat entre les deux concurrents fût vidé par le pape et par l’empereur d’Allemagne[3]. Plus tard, en 1094, au milieu des différends survenus entre Henri IV et Poppon, évêque de Metz, le chef de l’Empire conféra au comte de Looz la part que l’Église de Metz possédait dans la domination seigneuriale du territoire de Saint-Trond.
