Il avait une relation avec Oda von HALDENSLEBEN.
CHRISTIAN, son of [GEBHARD I Graf von Querfurt/BURCHARD I Graf von Querfurt] & his wife --- . "Cristinus comes, frater Gebehardi de Quernvorde" is named father of Graf Wichmann in the Annalista Saxo, although according to Europäische Stammtafeln Cristin was the possible son of Gebhard I Graf von Querfurt. It is possible that he was the uterine brother of Graf Gebhard, especially as his is the only example of the name "Christian" in the Querfurt family.
Married ODA von Haldensleben, daughter of BERNHARD von Haldensleben Markgraf der Nordmark & his wife ---. The primary source which confirms her parentage and marriage has not been identified.
Graf Christian & his wife had two children:
1. WICHMANN von Seeburg (-[1115]). "Cristinus comes, frater Gebehardi de Quernvorde" is named as father of Graf Wichmann in the Annalista Saxo. Graf von Seeburg. m firstly GISELA von Schweinfurt, daughter of OTTO Markgraf von Schweinfurt Duke of Swabia & his wife Irmgard [Aemilia/Immula] di Susa. The Annalista Saxo names (in order) "Eilica, Iudhita, Beatrix, Gisla, Berta" as the five daughters of Otto von Schweinfurt and his wife Immula, naming Gisela's husband as "Wigmanno comiti de Seburch". Europäische Stammtafeln says that Gisela's first husband was Arnold Graf von Diessen. The Annalista Saxo makes no mention of such an earlier marriage. In addition, Gisela, wife of Arnold, was described as "uxor comitis Arnoldi" in the record of her death in the Diessen necrology, which suggests that she predeceased Arnold or at least that Arnold had been her only husband. In any case, if Gisela, wife of Arnold, had left Bavaria for Saxony to marry a second time it is less likely that her death would have been recorded at Diessen. Married secondly ([1096]) BERTHA von Camburg, daughter of WILHELM Graf von Camburg [Wettin] & his wife Geva Gräfin von Seeburg ([1075]-before [1152/56]). Her name is confirmed by the charter dated to [1149] under which her daughter Hedwig Abbess of Gernrode donated part of her inheritance from "matris…eius Berchte et fratris eius comitis Geronis" to Gernrode. The primary source which confirms her parentage has not yet been identified. Graf Wichmann & his second wife had three children.
2. WILHELM von Seeburg . The Annalista Saxo names "Willehelmus comes de Lutisburh" as brother of Graf Wichmann[. Graf von Lutisburg. 1067/75.
