ADALHARD [IV], son of ADALHARD [III] & his wife --- (-[2 Jan] 890). The primary source which identifies Adalhard [IV] as the son of Adalhard [III] has not yet been identified. However, the Catalogus abbatem Epternacensium names "Adelardus iunior comes" as [lay] abbot of Echternach in 878 until 890, suggesting that he may have had the same name as his father[407]. "Hludowicus…rex" confirmed a donation of property "in pago Muselahgeuui in comitatu Adalhardi villam…Berge" to Kloster Fulda by charter dated 24 Jul 880[408]. Emperor Karl III granted property "in Weitereiba in comitatu Adalhardi ad Rosbach" to Kloster Fulda by charter dated 7 Apr 884[409]. The Liber Memorialis of Remiremont records the death "IV Non Jan" of "Adellardus"[410], although it is not certain that this refers to Adalhard [IV]. Hlawitschka suggests that Adelhard [IV] married ---, [daughter of Matfried [II] & his wife ---], or daughter of Matfried's sister and that the couple were the parents of the three brothers Gebhard and Matfried Counts of Metz and Richer Bishop of Verdun[411].]
Possible children:
No source has yet been found which names the parents of the following five brothers. However, the fact that one is named Matfried suggests that they were sons of Adalhard [II] and his wife, assuming that she was the daughter of Matfried [II]. A descent from Adalhard [IV] is also suggested by the common use of the names Stephanus and Gerard in the two families.
