Siegfried I, count of Luxembourg - His parents

Hi Dimitry. It isn't Geni policy to add NN parents - they clog up searches and add no value. This profile is Relationship Locked so that incorrect parents can't be added.

If you have queries about Cunigunda, you'll need to add your Primary Sourced reasons for your opinion.

Origin
Siegfried is traditionally considered the son of Wiegerich, Count Palatine of Lorraine and Count of Bidgau [2] . Although the name of Siegfried's father is not mentioned in historical sources, in the 11th century a genealogy was created of Cunegonde of Luxembourg , the wife of the Holy Roman Emperor Henry II , linking her to the Carolingians . Siegfried's mother was shown to be Cunegonde , the daughter of Irmentrude and granddaughter of Louis II the Stammerer , King of the West Frankish Kingdom [3] . Later researchers identified her with Wiegerich's wife, who was also named Cunegonde [4] .

The relationship of the Wiegerichids with the Carolingians is supported by an act of the West Frankish king Charles III the Simple , who calls the future bishop of Metz Adalberon I nepotem (i.e. "nephew" or "grandson"). Adalberon was the son of Wiegerich and Cunigunde. However, Charles III did not have a sister or daughter named Cunigunde. In order to remove this contradiction, Leon Vanderkinder translated nepotem as "cousin" [2] . It is not precisely established who was Cunigunde's father.

Siegfried's relationship with the Wiegerichids is established on the basis of a letter dated 985, written by Gerbert of Aurillac . In it, he calls Siegfried patruus (paternal uncle) of Gottfried the Captive , Count of Verdun . Gottfried was the grandson of Wiegerich, on the basis of which Siegfried is considered the son of Wiegerich. Onomastic data also support the hypothesis of Siegfried's belonging to the Wiegerichids : among the children of Siegfried there are the names Kunigunda, Liutgarda, Adalberon, Friedrich, Giselbert, which are characteristic of the Wiegerichids.

There are, however, chronological problems which prevent the version that Siegfried was the son of Wiegeric from being fully accepted. Wiegeric died no later than 919. Adalberon became bishop of Metz in 929 and was born no later than 909. Then Cunegonde, Wiegeric's wife, must have been born in the second half of the 880s, but her mother Ermentrude could not have been born earlier than 876 and, in that case, could not have been Cunegonde's mother. Furthermore, Siegfried himself, if he were the son of Wiegeric, must have been born no later than 919. Moreover, he is not mentioned in a deed dated 943, written by the widow of Goslin , Count of Bidgau, son of Wiegeric, to which three other brothers of Goslin signed [5] . However, he first appears in historical sources only in 959. Siegfried's children were born in the 950s–980s. Based on these data, it is more likely that he was born in the 930s or 940s and therefore could not have been the son of Wigerich [6] . In order to explain the discrepancies in chronology, a version has been proposed according to which Siegfried was not the son, but the grandson of Wigerich. In this case, his mother, Kunigunde, is not identical to Kunigunde, Wigerich's wife.

There are arguments, however, that cast doubt on Siegfried's relationship with the Wiegerichids. There was constant antagonism between the Wiegerichids and Siegfried's descendants, which was not very typical for feudal families in the early Middle Ages, in which relatives usually supported each other. In addition, there were several marriages between the Wiegerichids and Siegfried's descendants, and the Catholic Church forbade marriages between close relatives. For example, Friedrich , Siegfried's son, married the granddaughter of Gerberga, the sister of Count Gottfried. Leon Vanderkinder considers her to be the daughter of Gozlin, Count of Bidgau, and the sister of Gottfried the Captive, Count of Verdun [2] . However, not all researchers agree with this identification. According to another version, Gerberga's brother could have been Gottfried of Metz , Vice- Duke of Lower Lorraine .

In order to resolve such contradictions, researchers also put forward other versions of Siegfried's origin. According to one version, Siegfried could have been the son of Rikuin , Count of Verden, and Kuniguda, the widow of Wiegerich. However, Rikuin died in 923/924, so this version also has problems with chronology [6] . In order to resolve chronological problems, some historians consider Siegfried to be the son of Kuniguda from a hypothetical third marriage concluded after Rikuin's death [7] , but there is no documentary evidence of such a marriage.

a) SIEGFRIED ([925/35]-28 Oct [998], bur Trier). As noted above, Siegfried is shown here, for presentational purposes, as the son of Cunigonde by her possible third husband, but the possibility cannot be excluded that he was Siegfried, son of Wigerich [III] Comte d’Ardenne (in which case he would have been born [915/19] not [925/35] as suggested above). His relationship with Wigerich’s family is indicated by Gerbert of Aurillac who refers to "Godefridum, patruumque eius Sigifridum" in a letter dated 985 addressed to "dominæ Teuphanu Imperatrice" after he visited the pair in prison following their unsuccessful defence of Verdun against Lothaire King of the Franks[18], other letters clarifying that "Godefridum" was Godefroi Comte de Verdun, grandson of Wigerich [III]. In [950], Otto I King of Germany transferred the abbey of Echternach as an imperial fief to Siegfried "advocatus altaris", who became Vogt/avoué (see below) and obtained privileges in 973 (see below), 980 and 992[19]. Siegfried owned scattered properties in Feulen, Hosingen and Monnerich (in the pagus Wabrensis) and at Berncastel and Roussy (in the pagus Mosellanus)[20]. Graf/Comte [von/de ---]: Bruno Archbishop of Köln confirmed an exchange of property "Baldau, quam Sigifredus comes ut acquireret" [translated by Vanderkindere as "Bodeux que menaçait Sigefroid"[21]] for "in villa Nohas…in pago Heislensi in comitatu Tulpiaco" between the abbot of Stavelot and "comite Warnero [Werner Graf von Zülpich, see the document LOWER LOTHARINGIA NOBILITY] fideli nostro...cum consensu uxoris et filiorum...suorum" by charter dated 31 Oct 953 ("regnante rege Ottone fratre nostro, anno xviii, Godefrido duce")[22]. Siegfried’s county has not been identified. His use of the comital title, before he acquired the castle of Luxembourg, suggests that he inherited substantial property holdings from his father, who would presumably also have been “Comte/Graf”. Comte [de Luxembourg]. "Sigefridus comes de nobili genere natus" received the castle of Luxembourg from St Maximin, Trier in exchange for property "villa Feulen in comitatu Giselberti comitis in pago Arduenne in villa…Viulna [et]…in pago Mathingouui in comitatu Godefridi comitis super ripem Alsuntie fluminis" by charter dated 17 Apr 963[23]. Gade reproduces a photographic copy of the original charter[24]. "Uda…comitissa" donated property "in pago Rizzigowi cui Egylolfus comes" to St Maximin at Trier "pro remedio…seniorique mei Gozlini necnon filiorum meorum Henrici…et Reginheri, Godefridi quoque et Adalberonis" by charter dated 18 May 963 witnessed by "Sigefrido comite, Richwino comite"[25]. "Sygefridus comes indignus...et coniunx mea Hadeuuig filiusque noster Henricus" exchanged “ex rebus mee proprietatis in pago Saroensi in villa...Odouuinesluica...et in comitatu Bedensi...” with Heinrich Archbishop of Trier for “in comitatu Bedensi monticulum qui antea uocabatur Churbelun nunc autem Sarburch situm super fluuium Sarouue et...” (for life) by charter dated 17 Sep 964[26]. Vogt of Echternach: "Otto…imperator augustus" granted property to Kloster Echternach by charter dated 15 Mar 973 which names "comitis Sigifridi fidelis nostri"[27]. Vogt of St Maximin at Trier: Archbishop Egbert donated property "de beneficio Luthardi comitis…mortuo sine herede" to Trier St Paul by charter dated 981, subscribed by "…Sigefridi comitis et rerum S Maximini advocatis…"[28]. He captured Wicfred Bishop of Verdun, who had attacked Siegfried's territory, at Vandresel but released him in [984]. Richer records that "Belgicæ dux Theodericus, necnon et vir nobilis ac strenuus Godefridus, Sigefridus quoque vir illustris, Bardo etiam et Gozilo fratres clarissimi et nominatissimi" captured Verdun in 985[29]. Siegfried helped defend Verdun against Lothaire King of the West Franks in [984/85], but was captured together with Godefroi Comte de Verdun [Wigeriche][30]. The necrology of Ranshofen records the death "V Kal Nov" of "Sigefridus Kunuz pater Chunigundis imperatricis"[31]. The necrology of Gorze records the death "VI Kal Nov" of "Seifredus comes"[32]. The year of Siegfried’s death is uncertain but is assumed to have been around [998]. Siegfried is named "Siefredi Saxonum ducis" by Rodulfus Glaber when recording the marriage of his daughter to Heinrich II King of Germany[33]. No other primary source has been identified which either accords the ducal title to Siegfried or directly links him to Saxony. The editor of the MGH SS edition of the text suggests that “all Germans called themselves Saxones” and that “all those in powerful positions adopted the title dux” ("omnes Germanos dicere videtur Saxones, omnes potentiores ducis nomine ormat")[34]. m (before 964, [960?]) https://fmg.ac/Projects/MedLands/LUXEMBOURG.htm#fatherSiegfriedMCun...

Thank you for raising it, Dmitry. You make very interesting points.
Hopefully we can get other managers with knowledge in this area to engage with the question here too.
Today, I'm probably not going to be able to get back here, but can you please bump me next weekend to take a look again?

Researching and debating medieval searches is such a valuable exercise.
