  Research Notes:

The Annales Egmundani name "Hildegardis comitissa" as wife of "Theodericus comes secundus [Hollandensium]" but do not give her origin. The wife of Count Dirk II was the daughter of Count Arnoul according to Rösch, but the author cites no primary source in support of this assertion. According to Europäische Stammtafeln, Hildegard was the daughter of Count Arnoul by Adela de Vermandois and was born in [934]. This appears difficult to sustain chronologically if Hildegard's first son was born in [950], although it is not impossible. Assuming that her sister Liutgard was born in 935, there is little time for the birth of an earlier daughter after Count Arnoul's marriage in 934, assuming also that the latter date is correct. This suggests that, if Hildegard was the daughter of Count Arnoul, she was born from an earlier otherwise unrecorded marriage. An alternative parentage is suggested by the Chronologia Johannes de Beke which records that Count Dirk II married "Hildegardim (ut creditor) filiam Ludovici regis Francie". This is chronologically impossible.... Hildegard daughter of Louis III King of France would have been too old for the marriage and any daughter of Louis IV King of France would have been too young.  It is also unlikely that the wife of Count Dirk II was a daughter of Charles III "le Simple" King of France, the birth dates of whose daughters are estimated to [908/16].  There therefore seems no possibility that the Chronologia could even be partially correct in assigning this possible Carolingian French origin to Dirk's wife, although it is curious how this origin came to be included in the source.  "Theodericus comes et uxor sua Hildegardis" are named in a charter dated Oct [967/79]. "Theoderici et Hildegardis" subscribed a charter dated 30 Sep 975, before "Arnulfi filii eorum [Theoderici et Hildegardis]".

The Chronologia Johannes de Beke records the death "III Id Apr" of "Hildegardis…sua conthoralis" and her burial at Egmond monastery. The Chronologia Johannes de Beke records the death "III Id Apr" of "Hildegardis…sua conthoralis" and her burial at Egmond monastery. Beke's Egmondsch Necrologium records the death "IV Id Apr" of "Hildegardis uxor [Theoderici 2 comitis] filia Ludovici regis Francie". Europäische Stammtafeln shows 990 as Hildegarde´s year of death... ¹
