Notes par Udo van Limburg

UDO, son of --- (-[1065/75] or 1078). Graaf van Limburg: "Comes Udo de Lemborch" donated a serf to the church of St Adalbert, Aachen by charter dated 1061[16]. Avocat of Saint-Trond: the Gesta Abbatem Trudonensium records in 1065 that, after “duce Frederico” [Frédéric Duke of Lower Lotharingia] was dead, confirmations were made regarding payments at the request of “domno Udone successore eius” and in the presence of “domni Adalberonis” [Adalbero Bishop of Metz, brother of the deceased Frédéric Duke of Lower Lotharingia][17]. A charter dated 1065 records the same confirmation: “Adalbero Metensis Episcopus”, noting the dispute between “germanum meum ducem Lotharingiæ Fredericum” and Saint-Trond regarding payments to the avocat, confirmed the situation in the presence of "domino Udone fratris mei successore [who had received “eamdem advocatiam in beneficio a nobis”]...et Ottone subadvocato"[18]. Udo presumably died before [1072/75], the estimated date of a charter, under which “Osmuth et Warburg” committed themselves to Saint-Trond, whose dating clause records “...Ottone advocato” [Otto de Looz Comte de Duras (see LOWER LOTHARINGIA NOBILITY, who was restored as full avocat of Saint-Trond after Udo died][19]. Kupper suggests that the following entry refers to Udo Graaf van Limburg[20]: the necrology of Prüm records the death in 1078 of “Udo comes”[21]. This date appears incompatible with Udo’s earlier loss of the advocacy, unless this was due to long-term incapacity before death or, assuming that Alternative (1) of Udo’s possible marriages shown below is correct, the death of his wife which would presumably have removed Udo’s legitimacy as Duke Frédéric’s successor.

The question of Udo’s possible marriage is speculative: it is not indicated directly in any surviving primary source. As explained in detail further below, two possible alternative cases may explain the ancestry of Udo’s successor, Hendrik [I] Graaf van Limburg. In each case, a possible marriage of Udo forms part of the overall picture and may help explain the hypotheses.

Under Alternative (1), Hendrik [I] would have been the son of Waléran [II] Comte d’Arlon. Consistent with this alternative, an explanation is needed for Hendrik’s predecessor in Limburg, Udo, succeeding Frédéric de Luxembourg Duke of Lower Lotharingia both in Limburg and in the advocacy of Saint-Trond. A marriage between Udo and an otherwise unrecorded older daughter of Duke Frédéric provides one possible explanation. If that is correct, Udo would have married before he was named at Limburg in 1061, and presumably his supposed wife would still have been alive in 1065 when Udo succeeded as avocat of Saint-Trond. For hyperlinking purposes only, this case would be: m ([before 1061]) --- de Luxembourg, daughter of Frédéric Duke of Lower Lotharingia [Luxembourg] & his first wife Gerberge de Boulogne ([1030/45]-after 1065).

Under Alternative (2), Hendrik would have been the son of Jutta [Judith], known daughter of Frédéric de Luxembourg Duke of Lower Lotharingia, by an unknown husband. Kupper suggests that Udo Graaf van Limburg was the unknown husband[22]. For hyperlinking purposes only, this case would be: m Jutta [Judith] de Luxembourg, daughter of Frédéric Duke of Lower Lotharingia [Luxembourg] & his first wife Gerberge de Boulogne. Kupper’s hypothesis is not entirely satisfactory. While this possible identification is an obvious one as Udo was Hendrik’s immediate predecessor in Limburg, Hendrik inherited Limburg from his mother whoever his father was. In addition, the absence of the name Udo among Hendrik’s known descendants also appears to suggest some doubt about his possible identification as Jutta’s husband. A further point is that, after Udo died, Hendrik did not inherit the advocacy of Saint-Trond, which passed to Otto de Looz Comte de Duras. The advocacy in fact passed from Otto’s son Giselbert to Hendrik’s son Walram in [1124/27], which suggests the resolution of a long-standing dispute which may be understandable if Hendrik’s right was not inherited from Udo in a direct line.

[Jutta & her husband (whoever he was) had [two] children]:
HENDRIK [I] van Limburg (-1119).
KONRAD von Merheim (-after 1088).
