HENRI de Louvain (-[1078/79], bur Nivelles).  The Annalista Saxo names "Heinricus comes et Reginherus" as brothers of "Adhela…nata de Brabancia ex castello quod dicitur Lovania seu vulgariter Lovene"[61].  The Chronicon Brabanti names "Henricum II Comitem et Marchionum" as son and successor of "Lambertus II qui et Baldricus dictus Cum-Barba" and his wife "Oda filia Gochelonis Ducis Loth"[62].  He succeeded his father as HENRI [II] Comte de Louvain.  m ADELHEID, daughter of EBERHARD Graaf van Betuwe en Teisterbant & his wife --- (-after 1086).  The Chronicon Affligemense names "Adela comitissa Lovaniensis" as mother of two sons "Heinrico et Godefrido" specifying that she was one of the founders of Afflighem Abbey[63].  "Adelheyt comitissa, comitis Everhardi filia" donated “predium suum Ortinam” [Orten (Bois-le-Duc)] to Utrecht St Marten, for the souls of “sue ac mariti sui Henrici...per manum Hermanni...advocatum”, by charter dated to [1076/99][64].  She founded the abbey of Afflighem in 1086.  Pope Eugene III records donations by "Vualterius qui dicebatur magnus…Gerardus filius suus…Alvericus et filius suus Reimerus…Adeloia venerabilis vidua" to Grimbergen abbey by bull dated 1 May 1147 which confirms the abbey´s privileges[65].  The identity of "Adeloia…vidua" is uncertain, but she may have been the widow of Henri [II] Comte de Louvain.  Comte Henri [II] & his wife had four children: 
1. Henri III, Count of Louvain, d. Feb. 5 1095
2. Godefroi, Count of Louvain, d. Jan 25, 1139
