  Research Notes:

Duke Frederic's parentage is deduced from the charter of "Otto…imperator augustus" dated 3 Jun 960, under which property was donated to Kloster St Petrus at Metz and which names "compater noster Adalbero…sanctæ Mettensis ecclesiæ presul [et] germano suo Friderico duce", read together with the diploma of Charles III "le Simple" King of the West Franks which granted the abbey of Hastières to the church of Liège which names the parents of Adalberon. "Friderici, Gisilberti, Sigeberti fratrum predicti Gozlini" subscribed the charter dated 943 which refers to "Gozlines…miles…ex nobilissimis regni Chlotarii ducens prosapia" and the donation by "uxor eius Uda et filius eius…Regingerus" to St Maximin at Trier. He constructed the château de Bar on land inherited from his wife, triggering protests from Louis IV King of France to Otto I King of Germany (the former considering the area within his sphere of influence) and from the Bishops of Toul (who considered that part of the land belonged to one of his churches).

Bruno Duke of Lotharingia, brother of Otto I King of Germany, to whom the latter had granted Lotharingia in 953, created the duchy of Upper Lotharingia in 959 and appointed Frédéric as FREDERIC I [associate] Duke of [Upper] Lotharingia. From the death of Duke Bruno in 965, the duchy was held under the direct authority of Emperor Otto I and his successors. Duke Frédéric attended the grand assembly of nobility and clergy convoked by the emperor at Köln 2 Jun 965. "Fredericus…Lothariensium Dux" confirmed donations of property at Murecourt to Bouxières by charter dated 26 Oct 966, signed by "Teutberti comitis, Lictardi comitis, Widonis comitis…". The Franco/German dispute over Lotharingia and Bar was pursued by Lothaire King of France who fought lengthy campaigns to recapture Lotharingia, culminating in the invasion of 978, the capture of Aachen, and the siege of Metz, although the French were forced to retreat by Otto II King of Germany.

The necrology of Fulda records the death in 978 of "Fridurih dux". 1
