Saint Gudula was born in the pagus of Brabant. According to her 11th-century biography, written by a monk of the abbey of Hautmont between 1048 and 1051, she was the daughter of a duke of Lotharingia called Witger and Amalberga of Maubeuge. She died between 680 and 714.
Reginar IV, Count of Mons, in Hainaut, was the son of Reginar III and Adela. His father died in exile in Bohemia in 973.

Godfrey III, called the Bearded, was the eldest son of Gothelo I, Duke of Upper and Lower Lorraine.
Gothelo, called the Great, was the duke of Lower Lorraine from 1023 and of Upper Lorraine from 1033. He was also the margrave of Antwerp from 1005 and count of Verdun. Gothelo was the youngest son of Godfrey I, Count of Verdun, and Matilda, daughter of Herman, Duke of Saxony. On his father's death, he received the march of Antwerp and became a vassal of his brother, Godfrey II, who became duke of Lower Lorraine in 1012. Gothelo succeeded his brother in 1023 with the support of the Emperor Henry II, but was opposed until Conrad II forced the rebels to submit in 1025. When the House of Bar, which ruled in Upper Lorraine, became extinct in 1033, with the death of his cousin Frederick II, Conrad made Gothelo duke of both duchies, so that he could assist in the defence of the territory against Odo II, count of Blois, Meaux, Chartres and Troyes. It was during this time 1033-1034, that Gothelo clashed with Baldwin IV, Count of Flanders, concerning the march of Ename.

Count Lambert "the Bearded" was the first person to be described as a count of Leuven in a surviving contemporary record, being described this way relatively late in life, in 1003.

The Reginarids were a family of magnates in Lower Lotharingia during the Carolingian and Ottonian period. Their modern name is derived from the personal name which many members of the family bore, and which is seen as a Leitname of the family. At least two Dukes of Lotharingia in the 10th century belonged to this family. After a period of exile and rebellion, the two brothers who returned to power founded the first dynasties of the County of Hainault and County of Louvain. The latter were ancestors of the House of Brabant, Landgraves and later Dukes of Brabant, Lothier and Limburg. The Reginarid Brabant dynasty ended in 1355, leaving its duchies to the House of Luxembourg which in turn left them to the House of Valois-Burgundy in 1383. Junior branches of the male line include the medieval male line of the English House of Percy, Earls of Northumberland, and the German House of Hesse which ruled Hesse from 1264 until 1918, included King Frederick of Sweden and still exists today.

Adela of Louvain (d.1083) was margravine of Meissen and later, margravine of the Saxon Ostmark.
Gerhard of the Moselle, Count of Metz and possibly of Alsace, was a Lotharingian noble active in the early 11th century. He was a key figure within an alliance of Lotharingian nobles who were seen as opponents of Henry II, Holy Roman Emperor. This also put him in constant conflict with the king's loyal representatives in Lotharingia, his relatives in the family known to historians as the House of Ardenne–Verdun. Henry II was Gerhard's brother-in-law, as they had both married daughters of Count Sigfried, the ancestor of the counts of Luxembourg. He was also in the Ardenne dynasty, though his family came to be opposed to his Verdun cousins.
