In 1130, Arnold "Draeckenbaert" refused to recognize Godevaert I, count of Leuven, as Duke of Brabant. Godevaert was instated as duke by Emperor Hendrik V. Duke Godevaert II continues the battle against Arnold, but survives only for 4 years. In 1145, Arnold wins from Godevaert III, who was just a baby and is mentioned in old texts as Godevaert "in den wiege" (in the crib). Arnold dies, however, in battle.

ARNOLD van Grimbergen (-[1134 or 1137]). Godefroi Duke of Lower Lotharingia recorded a donation by “Arnulfus comes Aderschot cum duobus filiis suis Godefrido et Arnulfo” to Afflighem abbey of land in Buggenhout, Malre and Steenhuffel which was the inheritance of “Joannem filium suum”, placed as a monk at the abbey, by charter dated 1125, witnessed by "Arnulfus de Grembergis, Gerardus frater eius, filii comitis Arnulfi Godefridus et Arnulfus, Worwinus de Heverle et Reinerus filius eius…"[994]. Arnold and his brothers Gerard and Alveric are named in the charter dated 1129 which records the foundation of the abbey of Parcq[995]. A charter dated 1132 records that "Gualterus quidam nobilis qui in alodio sio sita erat" founded the church at Grimbergen, and that after he died "heredes eius Gerardus…et Arnulphus" (whose father and mother were buried in the church) acting "per legatum suum hominem quemdam Alvaricum" requested "domino Norberto" to install his monks there, and records donations by "prædictus Gualterus, Gerardus filius…Alvericus tertius filius suus"[996]. The death of "Arnoldus advocatus ecclesie Grimbergensis" is recorded in 1134[997]. The death of "Arnout die voecht van Grimbergen" is recorded in 1137[998].
