He is the son of Adolf II of Lotharingia count of Keldachgau, Vogt of Deutz (1002–1041).

From that point forth the succession of the counts of Berg is well enough documented. Adolf I of Berg left one son: Adolf II of Berg-Hövel, count of Berg, count of Auelgau and Siegburg, Vogt of Werden, founded the Altenberg Abbey (died 1090 or 1106).
