Conon, Count of Montaigu and Duras
Conon II( Cono)( d. 1189 or after), Count of Montaigu and Count of Duras, son of Godefroi, Count of Montaigu, and his wife Julienne, daughter of Otto II, Count of Duras.
The precise dates of Conon ’s rule are unclear.
In a charter dated 1175 donating property to the Knights Hospitaller, Conon's brother Gilles is referred to as former count and his brothers Pierre and Conon as Counts of Montaigu and Duras, respectively.
That same charter refers to their uncle Bruno the archdeacon, presumably their great- uncle Bruno, brother to Otto II, Count of Duras.
A later charter dated 1182 witnessed by Henri of Esch( a relative of Goffrey of Esch, compatriot of Conon I, Count of Montaigu), identifies Conon as Count of Montaigu and Duras.
In 1185, Conon and his brother Pierre donated all his properties to Sainte- Marie and Saint- Lambert in Liege.
These properties were not kept by the Bishop of Liege, who sold them to Gérard of Looz and Wéry of Walcourt.
Conon was not known to be married and left no heirs.
After Conon ’s death, his brother- in- law Wery II de Walcourt became Count of Montaigu and Clermont, whereas Gérard II, Count of Looz, became the Count of Duras, reflecting the relationship between Looz and Duras dating back to the first Count of Looz, Giselbert.
Gislebert of Mons calls him called' small in body, smaller in mind and knowledge'.
He reports he held the advocacy of Saint- Trond and other properties in fief from the Duke of Limbourg, and owed guardianship of the castle of Limbourg.
Since Conon failed to answer the Duke's summons, the latter seized his properties, keeping some and selling others to Count Gérard of Looz in 1189.
Conon attempted to sell his advocacy to the Duke of Brabant who then occupied Duras and harass St Truiden, leading to an armed conflict involving also the Count of Hainaut.
Gozelo II, Count of Montaigu
Gozelo II( died 1097), presumed Count of Montaigu, son of Conon, Count of Montaigu, and Ida of Boulogne, sister of Godfrey, first ruler of the Kingdom of Jerusalem.
As the eldest son of Conon, it is assumed that he became the count upon his father ’s death in 1096.
As reported by both Albert of Aix and William of Tyre, Gozelo and his brother Lambert( the heirs of the count of Mortagne) took a major role in the First Crusade, participating in the Siege of Nicaea in 1097.
They then joined the army of Robert II, Count of Flanders, marching on Antioch.
Gozelo never made it to the subsequent siege, dying of disease in Artah.
Gozelo left no heirs and was succeeded by his brother Lambert as Count of Montaigu.
Abd al-Muttalib
Abd al- Muttalib Shaybah ibn Hashim( c. 497 – 578) was the grandfather of Islamic prophet Muhammad.
Lambert, Count of Montaigu
Lambert (died 1140 or after), Count of Montaigu and , son of Conon, Count of Montaigu, and Ida of Boulogne.
Lambert was also Seigneur de Rochefort, Avoué of Dinant, and Avoué of Saint-Symphorien-des-Bois.
As reported by both Albert of Aix and William of Tyre, Lambert and his brother Gozelo took a major role in the First Crusade, participating in the Siege of Nicaea in 1097.
Lambert was present at the siege of Acre in 1098, which finally fell after four years.
He commanded one of the corps of the army of Godfrey of Bouillon, resulting in the capture of Antioch in 1098.
Along with his father and Peter the Hermit, he founded the Neumoustier Abbey.
Lambert was married although there is some confusion as to his wife.
Europäische Stammtafeln lists two possibilities.
First is Gertrud de Louvain, daughter of Henry III, Count of Louvain, and Gertrude of Flanders.
Second is an unnamed daughter of Giselbert, Count of Clermont.
The speculation on the second possibility is based on the connection between Lambert and the Counts of Clermont, but that connection is best explained by his paternal grandmother’s relationship with Clermont.
Lambert and his wife (presumed to be Gertrud) had three children:
Upon his death, Lambert was succeeded as Count of Montaigu by his son Godefroi.
Lyon Cohen
Lyon Cohen( 1868–1937) was a Polish- born Canadian businessman and a philanthropist.
He was the grandfather of singer/ poet Leonard Cohen.
Gilles, Count of Montaigu
Gilles( Ægidius)( died before 1193), was Count of Montaigu and Clermont, Count of Duras, son of Count Godefried of Montaigu, and his wife Juliane, daughter of Count Otto of Duras.
Gilles was also Seigneur of Rochefort, Seigneur of Jodoigne and advocate of Saint- Trond.
In 1174, Gilles married Laurette de Looz, daughter of Louis I, Count of Looz, and his wife Agnes von Metz.
They divorced childless in 1176.
Gilles contracted leprosy, giving up most of his lands to his brothers Conon and Pierre.
Gilles was succeeded as Count of Montaigu, Clermont and Duras by his brother Conon, possibly as early as 1175.
In a charter dated 1175 donating property to the Knights Hospitaller, Gilles is referred to as former count and his brothers Pierre and Conon as Counts of Montaigu and Duras, respectively.
He kept the lordship of Jodoigne and was then at least once referred to as count of Jodoigne.
( His mother had also referred to herself as countess of Jodoigne.
Leprosy, however, was not the end of his military life, as Gislebert of Mons as he and his brother Conon fought the duke of Louvain, for seizing Duras and Jodoigne, his only remaining allod.
They were able to recover Duras.
Moreover, he writes of his capture in the town of Namur by Baldwin V, Count of Hainaut, who held him captive for a long time.
Gilles and his brothers prepared to go on crusade, though Gilles probably never went ahead with this plan.
None of the brothers had heirs, and so arrangements were made for their possessions.
Kaya Alp
Kaya Alp was, according to Ottoman tradition, the son of Kızıl Buğa and the father of Suleyman Shah, who was, in turn, the grandfather of Ertuğrul, and the great grandfather of the Ottoman Empire founder, Osman I.
Conon, Count of Montaigu
Conon( also Cono or Cuno; died 1 May 1106) was a Lotharingian nobleman and military leader of the First Crusade.
He was one of the most prominent lords of the Ardennes, being the count of Montaigu, lord of Rochefort and advocate( defender) of the city of Dinant from 1064.
He was also one of the most important vassals of the bishop of Liège, holding the county of Huy from the church.
His chief seat was the castle of Montaigu, while the castle at Huy was the redoubt of the bishops.
Gozelo I, Count of Montaigu
Gozelon( died 1064), Count of Behogne and then Count of Montaigu, of unknown parentage.
He was also avoué of Saint- Barthélémy, Liège, beginning in 1043.
Onomastics would suggest that the name Gozelon implies a family connection with the House of Verdun, who had several men with this name and lived in the same Ardennes region.
Gozlin,
Count of the Ardennes, for example, had a grandson Gozelon, Count of Bastogne, the successor to his father Reginar.
Another one of Gozlin's grandsons( the son of Godfrey the Captive), was also known as Gozelo, but there is no direct evidence for a relationship.
In 1038, in an act witnessed by Gozelon, Gothelo the Great, Duke of Lorraine, Arnold I, Count of Looz, and an unknown count named Sigebold, the Archbishop of Trier Poppo von Babenberg restored the monastery of St. Matheus of Trier.
Gozelon apparently destroyed the church at Marly and was subsequently buried at the church of Saint Hubert, the Apostle of the Ardennes.
Gozelon married Ermentrude( Ermengarde) de Grandpré, daughter of Widrich I, Count of Clermont, and his wife Hersende.
Gozelon and Ermentrude had five children:
After the death of Gozelon, his widow Ermentrude married Fredelon of Esch and had at least one child, Giselbert, Count of Esch.
Members of the House of Esch could be seen in historical documents until the 13th century but then vanished.
Gozelon was the patriarch of the family of Counts of Montaigu that eventually merged with the Counts of Duras, and then with the Counts of Looz.
Gozelon was succeeded as Count of Montaigu by his son Conon, a knight in service of his brother- in- law Godfrey of Bouillon, the first ruler of the Kingdom of Jerusalem.
For further details on the transition from Gozelon to his son, see Conon( succession).
Godefroi, Count of Montaigu
Count Godefried (died 1161) was Count of Montaigu and Clermont by inheritance, and Count of Duras by virtue of his marriage.
He was also seigneur (lord) of Rochefort, and burger and advocate of Dinant.
His parents were Lambert, Count of Montaigu and Clermont, and his wife Gertrud.
Godfried married Juliane, daughter of Otto II, Count of Duras, and his wife Berthe of Valenciennes.
They had five children:
Upon the death of Godfried, his son Gilles inherited all three counties.
Pierre is also listed as a Count of Montaigu, but as he died before his older brother, it is not clear that he ever actually held the title.
After Conon's death, his brother-in-law Wery II de Walcourt became Count of Montaigu and Clermont, whereas Gérard II, Count of Looz, became the Count of Duras.
