The first known representative Gosuin Clutinc, is mentioned in 1138, perhaps as Alderman in Brussels in the founding charter-staffing of the hospital of Our Lady and XII Apostles. If we may hesitate on its Aldermen function (scabinus epithet end of the list the respect he?) and even its installation in town (if it is an institution typically urban, found in the list of witnesses traditional lords), it is evident that it is the closest ducal entourage. From 1145 to 1186, he appears indeed as a witness in nearly a dozen ducal charters (known spellings variables: Clubbinc, Clibbinc, cloting, Cleppinc). Note appearances in a trend for the ducal transactions in the northern region and northeastern Brussels to Antwerp, Leuven and Aarschot. Two endorsements attesting possessions and family ties Gosuin Clutinc confirm that this situation is not due to chance princely interventions, but that it probably corresponds to a zone of influence which may be from our character. In 1154, first, the Duke Godefroid III puts the Abbey of Sain-Michel in Antwerp in possession of the freehold of Nederokkerzeel and its Dependencies (the property extends to Wespelaar). Alienation was the subject of a challenged by heirs that the duke had decided by a judgment of the court. Among dependencies of this freehold held by children of Eppon van Nederokkerzeel, there is the earth Gosuin Clutinc. 1170, the problem does not yet appear quite resolved, since the Duke must enact again about this obviously played well. At this time, and following an agreement reached between the heirs and the Saint-Michel abbey, Godefroid III the institution carries all the rights in question that had been abandoned him for this purpose: among those who renounce their claims, there is Francon de List (whose descendants are known in the thirteenth century as lords in the region of Erps-Nederokkerzeel, see below) and all its children and other heirs, including Gosuin and Clutinc Godin his brother with whom he had property, it seems, in common .
Children and descendants of Gosuin also belong to the ducal entourage and some even seem settled in the city: in 1150, the son of Gosuin, Everard, mentioned in his sides in a charter of Godefroid III Abbey Kortenberg; in February 1186 Francon Clutinc, said Bruesella, witnesses a charter by which the Godefroid III Duke returned from his pilgrimage to Jerusalem, approves the donation made by Siger of Kraainem for Affligem Abbey during his absence.
At the turn of the twelfth-thirteenth century, the importance of Clutinc could be measured by the fact that one of them soon became an important holy prelate Brussels Boniface (ca. 1181-1260), was dean of St. Gudule (around 1216), Doctor of Theology of the University of Paris (1222-1229), schoolmaster in Cologne (1229-1231) and Bishop of Lausanne (1231-1239). Following an attack, he left his office and retired to the Abbey of La Cambre in Ixelles, where he remained until his death.
In the first half of the thirteenth century, a major Clutinc appear in the documentation: Walter Clutinc which one has a little less than fifty entries included between 1204 and 1245 suggests a multifaceted character in Brussels and the princely entourage. Walter, called several times Knight, is an important member of the court of Henry I dukes and his son Henry II (its presence as a regular witness acts of a diplomatic nature is significant), the lord of the entourage, qualified 1226 'Brussels', known as seneschal of Brabant in 1232 and 1235 qualified noble man in 1242, attested as a donor before 1229, a tithe of Wezembeek (next to Nederokkerzeel) at the Abbey de la Cambre. In 1229, it is reported as a witness in a charter of Walter V Aa and his brother Arnold and in 1243 in a Charter of Grimbergen Asse.
Around 1220, there is mention of a Francon Clutinc in the entourage of Duke Henry I to during the sale of several fiefs to the Abbey of La Cambre, while Renier Clutinc known in 1234 in a list of ducal witnesses quoted in first place Walter Clutinc.
By the middle of the thirteenth century, an Arnold Clutinc is known as keeper of the Church of Cologne Sint-Pieters-Leeuw.
In the second half of the thirteenth century, several Clutinc are active in Brussels and the peri-urban area. Renier Clutinc, son of William Clutinc, is known by many mentions, once with his brother Francon: Renier is alderman of Brussels 1267, major holder of land in the 1260s in the Brussels region (1263, it is overlord for a property situated in Forest, in the locality Overvliet) but also the side Roosbeek between Tienen and Boutersem (it is said on several occasions to "Roosbeek ") and Mathilde feudal lady in 1270. He died years later in 1289. His brother Francon Clutinc is attested in 1273 in England as wool merchan: from which it exports 20 bags.
Clutinc Walter son of Walter Clutinc (cited as such in 1235), is known from the late 1240s in a highly similar posture to that of his namesake father is Knight testified several times as frequently as a relative of the Duke, a recovery as a man of Arnold Kraainem or the Brussels Squire (this Used together with Gosuin Clutinc) and finally as the landowner near Brussels. In 1250, he was appointed arbitrator by the Duke in a loan deal between the latter and the Antwerp banker Hugues Nose, while in 1253, it is described as dominus. He died in 1270 at the latest.
We know at least part of the descendants of Walter Clutinc son. Simon is attested in 1251 alongside his father. Helewide his daughters, Mary and Gertrude are in years 1270-1280.
At the same time, also known Elizabeth, widow of Gerard said Clutinc, and their children Aleide, Margaret, Elizabeth and Ide. Ide married and her husband is called Jean bears the family name Clutinc.
The clerk Amelric Clutinc is known by two statements in 1271, of which evokes the existence his vineyard in Orsendal.
Gosuin Clutinc, seen here earlier with Walter Clutinc son in 1253, is still subject to a mention in 1272 as a vassal of the lady Mathilde and her husband Leon de Beersel (he then holds property in fee located in Molenbeek , not far from Brussels Beguine). His children, Henry, Englebert, Guillaume, Aleide, Helewide, Elizabeth, Catherine, Michael and Getrude are reported in the 1280-1290 years as landowners in Brussels and the surrounding area (Nieuwenrode, Wezembeek, etc.).
Towards the end of the thirteenth century, there are several children of Renier Clutinc, son of Willem: Walter Clutinc, Francon Clutinc (alderman of Uccle in 1291, alderman of Brussels from 1300) and Renier Clutinc.
At the same time, Aegide Clutinc and his son Jean are attested in the 1290s: Aegide is known as a knight, then as a brother in the abbey of Grimbergen (he died in later in 1292); his son Jean Clutinc is reported in 1292 as the Dukes servant
