Reginar II (890–932) was Lotharingian magnate who was active from approximately 915 to 932. He was brother of Duke Gilbert of Lotharingia, who died at the Battle of Andernach in 939, and because his son and grandson claimed it, he probably already personally held the fort of Mons in Hainaut as the seat of a county.
The County of Loon was a county in the Holy Roman Empire, which corresponded approximately with the modern Belgian province of Limburg. It was named after the original seat of its count, Loon, which is today called Borgloon. During the middle ages the counts moved their court to a more central position in Kuringen, which today forms part of Hasselt, capital of the province.
Count Richar was a 10th-century Lotharingian count. He had a well-attested county in the Luihgau, a territory between Liège and Aachen, and he is generally considered to have held comital status in the County of Hainaut, possibly in the area of Mons.
Balderic of Cleves was a long-reigning and influential Bishop of Utrecht from 918 to 975.
Giselbert van Loon is 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.
Iremfrid was a 10th-century noble born to a family which had its power base in the Rhine–Meuse delta region, near the modern border of the Netherlands and Germany. He was the eldest son of Ricfrid Count of Batavia, and his wife Herensinda. The memorial of Ricfried, which now only exists in several transcriptions, referred to him as either "Rector Yrimfredus" or "Victor Yrimfredus".
Count Nibelung or Nevelung, son of Count Ricfried and his wife Herensinda. He was probably his father's heir, and like his father he was probably a count in Betuwe (Batavia), and more generally in the Rhine-Meuse-Scheldt delta region, now in the Netherlands, and the neighbouring northern Rhineland in Germany. His better-known brother was Bishop Balderic of Utrecht.
Rudolf or Rodolphe, was a Lower Lotharingian noble born into a family with connections to Utrecht. He is thought by some modern interpreters to have later had lordships in the Hesbaye region which is now in Belgium, in a part which mostly came to be incorporated into the later County of Loon. He was a son of Nevelung, Count of Betuwe, and a daughter of Reginar II, Count of Hainaut, whose name is not known. He had two uncles, one paternal and one maternal, who were both named Rudolf, and various proposal have been made about how the three Rudolfs correspond to various references to "Count Rudolf" in the 10th century "low countries". Although his paternal uncle Rudolf is sometimes considered to have become a cleric, Jongbloed (2006) argued that he must have been a count, and that he certainly had a wife and offspring. There is no contemporary record of young Rudolf, the nephew, as a count, nor indeed as an adult.
Otto is a purported Count of Loon and father of Count Giselbert, who would have been adult roughly around the years 980–1000. He appears in only one much later document that is considered unreliable, so his existence is doubted. The list of the counts of Loon is normally started with Giselbert.
Lambert, was a Lotharingian nobleman with lands somewhere near modern Dutch Limburg, who was associated with Gembloux Abbey in French-speaking Belgium. Its founder Wicbert was possibly a relative. Although there are other proposals, he is generally considered to be the father of Bishop Ansfried of Utrecht and he was probably a brother of Ansfried the elder and Robert, the Archbishop of Trier.
The pagus or gau of Hasbania was a large early medieval territory in what is now eastern Belgium. It is now approximated by the modern French- and Dutch-speaking region called Hesbaye in French, or Haspengouw in Dutch — both being terms derived from the medieval one. Unlike many smaller pagi of the period, Hasbania apparently never corresponded to a single county. It already contained several in the 9th century. It is therefore described as a "Groẞgau", like the Pagus of Brabant, by modern German historians such as Ulrich Nonn.
Count Rudolf, was a count in Lower Lotharingia, who apparently held possessions in the Hesbaye region and in the area of Meuse river north of Maastricht. It has been proposed that he was a son of Reginar II, Count of Hainaut, and thus a member of the so-called Regnarid dynasty.
Count Emmo, Immo or Immon, was the name of at least one important Lotharingian nobleman in the 10th century, described by medieval annalists as a cunning strategist. Various life events of a nobleman of this name were recorded, although historians differ about exactly which records refer to the same person or people. The first record claimed for him shows him as a young noble granting land to a new vassal in the Condroz region in 934, a member of the entourage of Duke Gilbert of Lotharingia. During the revolt of Gilbert which ended at the Battle of Andernach in 939, he switched sides. After the revolt he was personally associated with the fort at Chèvremont, near Liège. It becomes difficult later in Immo's life to be sure that all records mentioning a count of this name are referring to the same person.
Werner, Count in Hesbaye was a count in Hesbaye, now in Belgium. During his life he held lands in the Condroz, and lands as far away as Zülpich, now in Germany. All the areas he was associated with were part of the Kingdom of Lotharingia, which during this period was no longer independent, but mainly under the control of Germany.
Renaud (or Reginald) (died 973), brother of Count Werner. According to Eduard Hlawitschka (de) they were probably members of the so-called "Matfried" noble clan (de).
Ansfried or Ansfrid, was a 10th-century count, who held 15 counties in Lotharingia, a former kingdom which contained the low countries and Lorraine, and which was coming under the control of the new Holy Roman Empire during his lifetime. He is sometimes referred to as "the elder" in order to distinguish him from his nephew, and apparent heir, Bishop Ansfried of Utrecht, who was also a powerful count until he became a bishop.
Baldrick I was bishop of Liège and abbot of Lobbes from 955 until his death on 29 July 959.
Baldrick II was bishop of Liège from 1008 to his death at Heerewaarden in what is now the Netherlands.
Arnulfof Valenciennes, was a 10th and 11th century count and perhaps sometimes a margrave, who was lord of the fort of Valenciennes, which was at that time on the frontier with France, on the river Scheldt. It was part of the pagus of Hainaut, in Lower Lotharingia, within the Holy Roman Empire.
Count Balderic of Upladium was a Rhineland count in the Holy Roman Empire, who held various estates stretching from the forest region of Drenthe in the north, to the area near Cologne, on both sides of the river Rhine.
