BURCHARD [III] (-[1177/78]). ["Nobiles: Burchardus comes Magdeburgensis civitatis et Burchardus filius eius...” witnessed the charter dated 19 Jun 1155 under which Wichmann Archbishop of Magdeburg confirmed that “mater mea Machtildis...collardante fratre meo Conrado” had donated property “in occidentali Thietforde iuxta civitatem Halberstadensem”, for the soul of “cognati mei Wicmanni”[1657]. “...Burchardus burgravius et filius eius Burghardus...” witnessed the charter dated 1159 under which Wichmann Archbishop of Magdeburg granted property to “Heriberto”[1658]. It is not possible to be certain whether these documents relate to Burchard [II] and his son Burchard [III] or to the latter and his son Burchard [IV].] Burggraf von Magdeburg. “...Burchardus burchgravius Magdeb. et frater eius Geuehardus...” witnessed the charter dated 10 Mar [1155/59] under which Wichmann Archbishop of Magdeburg confirmed the property of Halle St. Maria[1659]. [%E2%80%9C...Borchardus borggravius Magdeburgensis et frater suus Udo junior...” witnessed the charter dated 16 Nov 1180 under which Emperor Friedrich I confirmed Bremen’s rights over “castrum Stadii et burgum”[1660]. If this document relates to Burggraf Burchard [III] it must be misdated, not only because it post-dates his estimated date of death but also because the names of the witnesses indicate that it should be dated before the elevation of Burchard’s brother Udo to the bishopric of Naumburg. Another possibility is that the witness list is garbled, compiled from other earlier documents. A third possibility is that the document relates to Burchard [IV], in which case it represents the only reference to his brother named Udo.] Wichmann Archbishop of Magdeburg confirmed that “Magdeburgensis comitis Burchardi de Querenvort et filiis eius” donated “villam...Ruach” by charter dated 20 Nov 1161[1661]. Wichmann Archbishop of Magdeburg confirmed that “...Burchardi Magdeburgensis burchgravii” donated “molendino...in lacu Sale” by charter dated 1170, witnessed by “...Burchardus burchgravius, comes Thederucus de Birka, comes Burchardus de Valkensten et filius eius Theodericus...”[1662]. "...Burggraf Burchard zu Magdeburg..." witnessed the charter dated 7 May 1173 under which Emperor Friedrich I confirmed the foundation of Kloster Pleisner Landstrich[1663].

m MECHTILD von Gleichen, daughter of LAMBERT [I] Graf von Gleichen zu Tonna & his wife Mechtild --- (-[1200]). Her existence is confirmed by the charter dated 1151 under which Heinrich [I] Archbishop of Mainz confirmed the donation of property by "comes Lambertus senior quondam privignam suam…Adelhedim", which also refers to "filio suo Lamberto et…duabus filiabus suis"[1664]. A manuscript history of Querfurt church records that “Borchardum...in Magdeborch borggravius...filium suum...B.” married “filiam Lamperti comitis de Thuringia sibi coniugem Machildem...de cognatione Gerhardi comitis Arhe”, naming her “Mechtildem” in a later passage[1665].
