The Annalista Saxo states "genuit autem Liudolfus ex Gertrude comitissa Brunonem, qui iuxta villam Niethorp occisus est, et Ekbertum seniorem marchionem". In a later passage it names "Brunone et Ecberto comitibus, filiis Liudolfi de Bruneswic qui fuerat patruus regis". "Heinricus…Romanorum imperator augustus" donated "comitatum quem Brun eiusque filius noster frater Liutolfus nec non et eius filius Echbreht comites…in pagis Northduringen, Darlingen, Valen, Salthga, Grethe, Mulbeze" to the church of Hildesheim by charter dated 1051. The Annales of Lambert von Hersfeld record in 1057 that “Otto frater Wilhehelmi marchionis, sed matrimonio impari, matre...Slavia” had been exiled to Bohemia from boyhood but returned to Saxony after the death of his brother to claim his inheritance, fought “Brun et Eggeberdus patrueles regis”, killed “Brun”, and still “adolescentem” was killed by Ekbert.
Graf von Braunschweig. "Heinricus…rex" granted "comitatum Udonis marchionis" to the church of Bremen-Hamburg by charter dated 24 Oct 1063, with the consent of "Ottonis Baiuuariorum ducis, Bertoldi ducis, Ottonis marchionis, Fritherici comitis palatine, Ekkiberti comitis". "Heinricus…rex" granted property "duas villas Hochfeld et Suueichusen cum foresto Heiligenforst in comitatu Gerhardi comitis in pago Nortcowe" to the church of Hildesheim by charter dated 10[6]5, supported by "duce Ottone, Ekkiberto comite, item Gotescalco comite".
He was installed as EKBERT I Markgraf von Meissen in early 1067, as shown by the charter dated 5 Mar 1067 under which "Heinricus…rex" donated property "in pago Istria in marcha Odalrici marchionis" to the church of Freising supported by "Ekkiberti marchionis, Odalrici marchionis". He is not, however, referred to by the title Markgraf in two subsequent charters: "Heinricus…rex" granted property "Asingvu in pago Chunzingowe et in comitatu Ekkiberti comitis" to "mulieri cuidam Lantwich" by charter dated 1067[59], and "Heinricus…rex" granted property "villam Livbeni in pago Plisni in comitatu Ecberti comitis" to "Mecelino servienti nostro" by charter dated 18 Jul 1068.
The Libro Memoriarum Sancti Blasii records the death in Jan 1068 of "Eghbertus marchio". 1
