His parentage is confirmed by the anonymous continuation of the Chronicle of Robert of Mont-Saint-Michel which records that "filius eius Reginaldus Comes Boloniæ" donated property to Jumièges for the soul of "Albericus Dammartini Comes". “Aubericus dominus Feritatis et uxor mea Mahaudis et filius meus Renaudus” donated dead wood “de Amaro Nemore domui de Retollu” to the church of Yerre by undated charter. Mathieu dates this charter to [1160/77]: maybe it can be dated more narrowly to [1168/75]. "Albericus comes Domni Martini et Raynaldus filius meus comes Boloniæ et Matildis uxor mea comitissa" donated property to Dammartin Saint-Pierre by charter dated 1185. "Radulfus comes Clarimontis" donated part of Hez wood to the church of Froidmont by charter dated 1190 witnessed by "Alberico comite de Dammartin et Renaldo filio eius…Aelidis uxor mea et filie mee Cathelina et Mathildis…Hugo frater meus primicerius ecclesie Mettensis…". He kidnapped his future second wife and kept her at the château de Riste in Lorraine, where he lured her fiancé (Arnoul de Guines Seigneur d'Ardres) and arranged his arrest by Albert de Hièrges Bishop of Verdun.
He succeeded in 1192 as Comte de Boulogne, de iure uxoris. "A. comes Domni Martini" donated property to Saint-Leu d’Esserent by charter dated 20 Sep 1200, signed by "M. comitisse Dampni Martini uxoris mee et…R. comitis Bolonie filii nostri".
He succeeded his father in 1200 as Comte de Dammartin. “Reginaldus comes Bolonie” donated property to Jumièges, for the soul of “Alberici patris mei comitis Dampnimartini in eadem ecclesia sepulti”, with the consent of “Yde uxoris mee comitisse Bolonie, Radulfi et Simonis fratrum meorum et sororum mearum”, by charter dated [19 Sep/Dec] 1200.
Philippe II King of France installed him in 1205 as Comte d'Aumâle and in 1209 as Comte de Mortain. He swore homage to John King of England in 1212, and his assets in France were confiscated in King Philippe II. He was captured after the battle of Bouvines in 1214 and imprisoned at the château de Goulet where he later committed suicide. 1
