OTTO, son of KONRAD Duke [of Lotharingia] & his wife Liutgard of Saxony (-4 Nov 1004, bur [Bruchsal]). The Chronicle of Alberic de Trois-Fontaines names "Ottonem" as son of "duci Wormatie Conrado", specifying that he was father of "Cono dux et Henricus pater imperatoris Conradi"[360]. Graf im Nahegau 956: "Otto…rex" granted property "in pago Nahgouue in forasto…Vuasago…in comitatu Ottonis filii Cuonradi ducis" to Worms St Peter by charter dated 8 Mar 956[361]. He was installed as OTTO Duke of Carinthia by Otto II King of Germany in 978 after the trial of Heinrich Duke of Carinthia who had been implicated in the rebellion of Heinrich II "der Zänker" Duke of Bavaria[362]. Duke Otto was deprived of Carinthia in 985 when it was returned to Duke Heinrich I [Liutpoldinger], but allowed to retain the ducal title and granted lands around Worms and Frankfurt[363]. He was restored as Duke of Carinthia from 995 to 1002. Presumably he is the "Duke Otto" who is listed first among those presiding over a court hearing in the presence of Emperor Otto III at Pavia 14 Oct 1001[364]. According to Thietmar, he was proposed as candidate for the imperial throne in 1002 but declined the offer[365]. Thietmar names "Duke Otto of Carinthia and Verona" among those sent by Heinrich II King of Germany to Lombardy after his election to quell unrest[366]. Wipo names "Ottone duce Francorum" when recording the names of his sons[367]. The necrology of Fulda records the death "1003 II Non Nov" of "Otto dux"[368].
m JUDITH, daughter of --- (-991, bur Worms Cathedral). "Chuonradus… Romanorum imperator augustus" donated property to the church of Worms naming "filii nostri Heinrici Regis, filie quoque nostre Beatricis" for the souls of "parentum nostrorum defunctorum atavi nostri ducis Chuonradi, avie nostre Iudithe, patris nostri Heinrici, patrui nostri ducis Chuonradi eiusque coniugis Mathildis, sororis etiam nostre Iudithe", all buried at Worms Cathedral, by charter dated 30 Jan 1034[369]. According to Wegener[370], Judith was the daughter of Heinrich, son of Arnulf Duke of Bavaria [Liutpoldinger], but he cites no primary source to support the suggestion.
Duke Otto & his wife had [four] children
