Otton, duc de Basse-Lotharingie

1. OTTO ([970]-13 Jun [1013/14], bur Maastricht, St Servatius). The Gesta Episcoporum Cameracensium names "defuncti ducis Ottonis, filii Karoli"[202]. He succeeded his father in 991 as Duke of Lower Lotharingia. Sigebert records that "Karolus dux" died in 991 and that "Otto filius eius" succeeded in the duchy of Lotharingia[203]. The Gesta Abbatem Trudonensium names "Ottoni duci Lotharingiæ, suo consanguineo [=Henricus imperator]" when recording his opposition to "Metensis episcopus Theodericus secundus" and usurpation of the possessions of the church of Metz (including the abbey of St Trudo) in 1005 during the rebellion of the latter[204]. The same text refers to Otto leaving an only daughter, which suggests that he died soon afterwards, although it is not impossible that the chronicle conflates two distinct events. In any case, conclusions drawn from this passage cannot be definitive as the part of the chronicle in question is incomplete[205]. Some corroboration is found in the Chronicle of Alberic de Trois-Fontaines which records the death of "duce Ottone, filio ducis Karoli" in 1005[206]. Sigebert also records the death of "Ottone duce" in 1005, adding that the duchy of Lotharingia was granted to "comiti Godefrido, filio Godefridi Ardennensis"[207]. However, it is not possible to treat these passages as conclusive as regards the date of Otto's death. The thrust of both texts is the recording the appointment by the emperor of Godefroi (son of Godefroi Comte de Verdun) as Duke of Lower Lotharingia "mortuo duce Ottone", an event which is recorded elsewhere as taking place in 1012. The necrology of Liège Saint-Lambert records the death "VII Id Jun" of "Ottonis ducis"[208].

[m ---. If it is correct, as shown below, that Otto was the father of a daughter, the name of his wife is not known.] Duke Otto & his wife had one possible child:

• a) [daughter . The Gesta Abbatem Trudonensium records that "Ottoni duci Lotharingiæ…" left an only daughter, whom it later identifies as "Hermegardam Namursi cometissam"[209]. As shown below, other sources indicate that Ermengarde, wife of Albert I Comte de Namur, was the daughter of Duke Otto's father. The sources discussed in the document NAMUR indicate that Ermengarde was the mother of at least three of the children of Comte Albert. This would be chronologically impossible if she had been the daughter of Duke Otto.]

Otto (c. 970–1012) was the duke of Lower Lorraine from 993 until his death. He was the son of Charles, son of King Louis IV, and his first wife, a daughter of Robert de Vermandois, count of Meaux and Troyes.

When his father left the duchy to fight Hugh Capet for the throne of France in 987, he became regent in Lower Lorraine when still apparently under twenty. Charles was defeated definitively in 991 and died two years later a prisoner in Orléans. Otto then succeeded into the full dukeship. In 1002, at the death of the Holy Roman Emperor Otto III, he was one of the loyal nobles who accompanied his body from Paterno to Aachen. According to the Chronica of Sigebert de Gembloux, he died in 1006, but he seems to be alive as late as 1012, when Count Godfrey II of Verdun succeeded to the duchy.

His wife is unknown and had no known issue.

Otto was one of the last legitimate male-line descendant of Charlemagne and thus the Carolingian dynasty. His cousin, Arnulf, archbishop of Rheims, was illegitimate. The counts of Vermandois were direct male-line descendants of Charlemagne through Bernard, king of Italy, illegitimate son of Pepin of Italy. Although Otto was seemingly the last legitimate Carolingian, there remained illegitimate male lines, possibly also others than just the Vermandois.
