  Research Notes:

His parentage is deduced from the Chronologia Johannes de Beke which records that Charles II "le Chauve" King of the West Franks granted "ecclesia Egmondensem et Kinhem a Zuitgerdes-Haga" to "Theodrico fratri Walgeri principis" in 863 at the request of "comitis Haganonis".... The same grant of land is also referred to in the charter dated "XVII Kal Iul…anno XXX regnante domno Karolo rege", under which "Karolus…rex Francorum" granted property "Suuithardeshaga usque Fortrapa et Kinnem" to "fideli nostro…Theoderico" in the presence of "Hagano…comes", which is more credible from a chronological point of view, on the assumption that "Karolus…rex Francorum" is Charles III "le Simple" King of the West Franks not Charles II "le Chauve". The document makes no reference to Dirk's family relationship with Waltger. The Annales Egmundani state that Ludwig II "der Deutsche" King of the East Franks granted "forestum Aewasda" to "Theodorico comiti Hollandiæ" in 867 at the request of "Hemma regina", and incidentally also confirm that the same Count Dirk had been granted "Ekmundam…et aliis…inter Forthrepam et Sintherthes" in 863. This text is also dubious from a chronological point of view. The corresponding charter is dated "DCCC[C]LXVIII[I] Id Apr…regnante domno Loth[ario] anno XV", under which "Loth[arius]…rex" granted property "forestum Was[el]a" to "nostro fideli…Theoderico comiti" at the request of "coniunx nostra Hemma regina", although the text contains contradictions which suggest that it is spurious. "Hemma regina" was the wife of Ludwig II "der Deutsche" King of the East Franks, whereas Lothaire II was the king of Lotharingia (whose territory included the Low Countries) who had ruled for fifteen years in 869. The Oorkondenboek van Holland en Zeeland dates this charter to 969, on the assumption that it refers to Count Dirk II, but if that is correct the grantee would have been Emperor Otto I. On the other hand, if the correct date was 869, the only other reference to a Count Dirk around that time is the dubious reference in Beke's Chronologia.

He is known to history as DIRK I Count of Holland, although it is unlikely that he used this territorial epithet at the time. He founded the monastery at Egmond. "Theodericus…Holtlandensis comes…Florentii filius" recites the ownership history of properties claimed by the church of Utrecht in Holland, including the foundation of Egmond church by "Theodericus, frater Waldgeri, cum legitima coniuge sua Geua", by spurious charter dated 26 Jul 1083, probably written in [1130]. Charles III "le Simple" King of the West Franks restored Kloster Susteren to the abbey of Prüm by charter dated 19 Jan 916 which names "fidelium nostrorum…Widricus comes palatii, Richuuinus comes, Gislebertus, Matfridus, Beringerius comites, Theodericus comes, Reinherus comes, Erleboldus comes, Uualcherus comes". "Gysalbertus dux rectorque S. Traiectenses ecclesie" donated property "Gulisam…in pago [Ardunensi] in comitatu Everhardi" to Trier by charter dated 928, subscribed by "Walgeri comitis, Thiedrici comitis, Cristiani comitis, Folcoldi comitis". Flodoard's Annals record that "Gislebertus…dux et Otho, Isaac atque Theodericus comites" offered the French crown to Louis IV "d'Outremer" King of the West Franks in 939. "Dominus Theodericus comes…cum…coniuge sua…Geva" donated property "in villa Franla…in villa Allecmere…in villa Callinge" to the church of Egmond, and "dominus Theodericus junior filius prefati Theoderici" exchanged property "in orientali parte fluminis…Fle" for property "in villa Nienthorp", by undated charter. "Theoderici" is named in charters dated Dec 941 and 11 Mar 948, and "Teoderici comitis" is named in charters dated 10 Jul [936/41] and 8 Jul 949. ¹
