He is married to Hildegard van Vlaanderen..
DIRK ([920/30]-Egmond 6 May 988, bur Egmond). The Annales Egmundani name "Theodericus secundus comes filius Theoderici primi". The Chronologia Johannes de Beke records that "Theodricusâ¦secundus Hollandie comes" was the only son of "Theodricus primus Hollandie comes" & his wife. His birth date range is calculated from his own estimated marriage date and the estimated dates of birth of his descendants. "Dominus Theodericus comesâ¦cumâ¦coniuge suaâ¦Geva" donated property "in villa Franlaâ¦in villa Allecmereâ¦in villa Callinge" to the church of Egmond, and "dominus Theodericus junior filius prefati Theoderici" exchanged property "in orientali parte fluminisâ¦Fle" for property "in villa Nienthorp", by undated charter. He succeeded his father as DIRK II Count of Holland, although the date is not known. "â¦Isaac comitis, Arnulfi filii eius, Theoderici comitisâ¦" signed the charter dated 8 Jul 941 under which "Arnulfusâ¦regisâ¦marchysus" restored property to Saint-Pierre de Gand, although it is not known whether this charter refers to Count Dirk I or Count Dirk II. "Theoderici comitis" subscribed charters dated 5 May [951/963], 29 Jul [955/64], 18 Oct 962, 28 Mar 967, 13 Apr 969 and 31 Jan 972. "â¦Baldwini advocati, Theoderici comitisâ¦" signed the charter dated 5 May 962 under which "Arnulfus marchysus" donated property to Saint-Pierre de Gand. According to Nicholas, after the death of Arnoul I Count of Flanders in 964, Count Dirk occupied Gent and Waas, taking advantage of the weakness of the government of the county of Flanders during the minority of Count Arnoul II. However, this may be speculation based on an interpretation of the charter dated "DCCC[C]LXVIII[I] Id Aprâ¦regnante domno Loth[ario] anno XV", under which "Loth[arius]â¦rex" granted property "forestum Was[el]a" to "nostro fideliâ¦Theoderico comiti" at the request of "coniunx nostra Hemma regina".
m ([945/50]) HILDEGARD, daughter of --- (before 933-10 Apr 990, bur Egmond). "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 Annales Egmundani name "Hildegardis comitissa" as wife of "Theodericus comes secundus [Hollandensium]" but do not give her origin. "Theodericusâ¦Holtlandensis comesâ¦Florentii filius" recites the ownership history of properties claimed by the church of Utrecht in Holland, including the further construction of the church by "Theodericus secundus, predicti filius, cum Hildegarda coniuge sua", by spurious charter dated 26 Jul 1083, probably written in . According to Rösch, she was Hildegard de Flandre, daughter of Arnoul I Count of Flanders, but he cites no primary source on which this is based. Her naming her two sons Arnulf and Egbert suggests that the affiliation may be correct. Boer & Cordfunke refer to a 938 meeting, between Count Dirk I, Count Meginhard of Hamaland, and Count Arnulf I of Flanders and his wife Adela, to arrange the betrothals of Hildegard of Flanders and Count Dirk II (son of Count Dirk I), and of her sister Liutgard and Wichmann of Hamaland (son of Count Meginhard). The meeting is alleged to be recorded in the Verbrüderungsbuch der Abtei Reichenau, but no trace of this has been found in the copy consulted. According to Europäische Stammtafeln, Hildegard was the daughter of Count Arnoul & his wife Adela de Vermandois and born in . However, from a chronological point of view it is more likely that Hildegard was born from an earlier unknown marriage of Count Arnoul, as explained in the document FLANDERS, assuming that she was Count Arnoul's daughter. The Chronologia Johannes de Beke records that Count Dirk II married "Hildegardim (ut creditor) filiam Ludovici regis Francie".
Count Dirk II & his wife had [four] children:
ARNULF ([Gent] [950/55]-killed in battle Winkel, West-Friesland 18 Sep 993, bur Egmond).
EGBERT (-8/9 Dec 993, bur St Andreas).
