"Ducis Godefridi eiusque fratris…marchionis Gozelonis" are named as present with Adalbold bishop of Utrecht at Driel, in an undated charter dated to before 1023, relating to the donation of Wamel[230].

The Chronicon of Bernold records the death in 1044 of "Gozzilo dux Lotharingorum"[238]. The necrology of Lüneburg records the death "19 Apr" of "Gozlinus dux"[239]. Heinrich III King of Germany regranted "comitatum…in Thrente" to the bishop of Utrecht by charter dated 22 May 1046, which specifies that the grant was made "post obitum Gozlini ducis nostre"[240]. m ---. The name of Duke Gozelon's wife is not known. Duke Gozelon I & his wife had six children:
a) GODEFROI ([1000/1015] -Verdun 30 Dec 1069, bur Verdun Cathedral). Herimannus names "Gotefridus alter filius eius [=Gozzilo dux Lotharingorum]" when recording his being passed over in the succession to his father[241]. The Genealogica ex Stirpe Sancti Arnulfi names "Godefridum ducem, Odam et Regelindam" as children of "Gozelo, frater Arnulphi et Godefridi"[242]. His birth date range is estimated on the basis of the estimated birth date of his father, and the more restricted birth date range of his sister Regelindis, although the absence of any information relating to his career before [1040] suggests that he may have been born in the later part of this period.
