This family, of Frankish origin, established a strong position in Franconia during the reign of Ludwig IV "das Kind" King of the East Franks. They eliminated their closest rivals the Babenberger family in 906. The succession of a member of this family to the German throne was seen as the obvious choice after the death without heirs of King Ludwig IV[149]. As will be seen in the analysis set out below, many of the family relationships in this family are speculative, based on the onomastic theories of Jackman.

UDO, son of GEBHARD Graf im Niederlahngau & his wife ---. Graf im Lahngau. 860/879.

m ---. The identity of Udo's wife is not known with certainty. According to Jackman[150], she may have been [Judith], daughter of Konrad Graf im Linz- und Argengau. King Arnulf in a charter dated 19 May 891 names "Chonradi…comitis et nepotis nostri"[151]. The speculation is that the relationship may have been through Konrad's mother who, if identified as the daughter of Konrad Graf im Linz- under Argengau, was the niece of King Arnulf's paternal grandmother Queen Hemma. However, an interesting puzzle is highlighted by the charter dated 10 Feb 910 under which "Hludouuicus…rex" confirmed the foundation of St Georg at Limburg-an-der-Lahn at the request of "Chuonrati ducis et fidelis neptis nostri, cuidam Chuonrato…comiti nostro filio Eberhardi in pago Loganahe in suo comitatu"[152]. "Chuonrati ducis et fidelis neptis nostri…" in this document is identified as the future Konrad I King of Germany, and therefore the son of Konrad who is named in the 891 charter. The two documents are therefore consistent in this respect when both are described as "nepotis" of King Arnulf and King Ludwig IV. However, "…cuidam Chuonrato…comiti nostro filio Eberhardi" is identified as Konrad "Kurzbold", son of Eberhard (killed in [902/03]) who is identified in other sources (as explained below) as the brother of the senior Konrad who is named in the 891 charter. The problem is that Konrad "Kurzbold" is not identified, either in the 910 charter or in other documentation in which he is named, as "nepos" of either of the Carolingian monarchs. One explanation could be that Konrad and Eberhard were born from different marriages of their father.

Udo & his wife had [four possible] children[153], who as shown below are confirmed as brothers in primary sources none of which mentions their parentage

UDO (-879 or after). The Annales Fuldenses record that the property of "Ernustum" was confiscated at a council in Regensburg in 861, and "Utonem quoque et Berengarium fratres eius, Sigihardum atque Gerolt comites Waldonemque abbatem" were banished as accomplices, specifying that "Uto et Berengarius cum Waldone fratre suo" went to France to "Karolum rege"[101]. The Annales Fuldenses record that "Werinharium quoque, Utonem et Berengarium comites a patre suo depositos" were promised the restoration of their dignities in 866
