Otto II, Count of Chiny

Otto II, Count of Chiny, son of Arnold I, Count of Chiny, and Adélaïs.
He succeeded his father in 1106 and completed the construction of the Abbey of Orval that his father had started in 1070, installing the canons in 1124. The installation of a Cistercian community in Orval in 1131 marked his last appearance in any proceedings.
He married Adelaide , daughter of Albert III, Count of Namur and Ida of Saxony. Their children were:

Ida, married to Godfrey I, Count of Leuven
Oda, married to Giselbert II, Count of Duras
Hugues, probably died young
Albert of Chiny
Frederick,, Provost at Reims from 1120
Adalbero II of Chiny-Namur, Bishop of Liège, 1135–1145
Eustache, married to a daughter of Wiger de Waremme, Avoué of Liège Saint-Lambert and Hesbaye. His son Louis de Lumaine was also Avoué of Hesbaye.

Ida and Godfrey I were parents of Adeliza of Louvain, wife of Henry I of England. Oda’s husband Gislebert was son of Otto, Count of Duras and therefore the grandson of Giselbert, the first Count of Looz, whose family would eventually be merged with the Counts of Chiny with the marriage of Otto's great-great granddaughter Jeanne, Countess of Chiny, with Arnold IV of Looz.
After his death, Otto was succeeded as Count of Chiny by his son Albert.
