Herbert of Wetterau (c. 930 – 992) was the son of Odo of Wetterau and a daughter (presumably named Cunigunde) of Herbert I, Count of Vermandois and Bertha de Morvis. Herbert was an important nobleman in central Germany and leader of the Conradines.

After the death of his father Odo of Wetterau in 949, Herbert became count of Kinziggau, Engersgau, and Wetterau. He also inherited the castle of Gleiberg, perched on basalt in the modern-day Giessen. In 976 Herbert got the count's rights for Gleiberg and vicinity: the county Gleiberg. Herbert also acquired the title of count palatine. In 981 he followed Emperor Otto II to Italy, and in 982, he took part in the disastrous Battle of Stilo against the Saracens.

He married Irmtrud of Avalgau (957 – 1020), daughter of Megingoz and Gerberga (daughter of Godfrey, Count Palatine of Lotharingia and Ermentrude, daughter of Charles the Simple and granddaughter of Otto I of Saxony).

Odo of Wetterau (c. 895 – 2 Dec 949) was a prominent German nobleman of the 10th century.

In 914, Odo was appointed Count of Wetterau and founded St. Mary's Church in Wetzlar. The Wetterau had been one of the counties of his father Gebhard, and Odo also acquired two other counties that had been his: Rheingau in 917 and Lahngau in 918.

Gebhard of Lahngau (c. 860/868 – 22 June 910), of the Conradine dynasty, son of Odo (died 879), count of Lahngau, and Judith, was himself count of Wetterau (909–910) and Rheingau (897–906) and then duke of Lotharingia (Lorraine).

In 903, Louis the Child, king of Germany, gave him the government of Lotharingia with the title of duke (Kebehart dux regni quod a multis Hlotharii dicitur). Gebhard died in battle against the Magyars, somewhere by Augsburg.

Udo was a 9th-century nobleman of East Francia, a son of Gebhard, Count of Lahngau, and older brother of Berengar I of Neustria. He and his brother were afforded their position in the March of Neustria both by kinship to Adalard the Seneschal and the favour of Charles the Bald.

Gebhard (died 879) was a mid-9th-century count in the Lahngau and the first documented ancestor of the dynasty later known as the Conradines. He was a "leading man of the [East] Franks" and a brother-in-law of Ernest, margrave of the Bavarian Nordgau. Gebhard may be a son of Odo I, Count of Orléans, if identical with Udo the Elder, count in the Lahngau from 821 to 826.

Odo I (French: Eudes; also Hodo, Uodo, or Udo in contemporary Latin) (died 834) was the Count of Orléans (comes Aurelianensium) following the final deposition of Matfrid until his own deposition a few years later.

He belonged to the Udalriching family and was a son of Adrian, who had also held the county of Orléans, and possibly of Waldrada, a Nibelungid. Odo first appears as an imperial legate to the Eastern Saxons in 810, when he was captured by the Wilzi. In 811, as count (comes), according to the Annales Fuldenses, he signed a peace treaty with the Vikings.

Adrian of Orléans (d. before November 821) was a Frankish count. His sister Hildegard of Vinzgouw married Charlemagne; therefore, he was the emperor's brother-in-law. He was the son of Gerold of Vinzgau and Emma of Alemannia.

Waldrada, who may have been a daughter of Wilhelmid Adalhelm of Autun,

Gerold of Vinzgau (also Vintzgouw or Anglachgau; d. 795) was a count in Kraichgau and Anglachgau. His daughter married King Charlemagne in 771. In 784 generous donations to the monastery of Lorsch by Gerold and Emma are recorded. He married by 758 to Emma (d. 789 or 798 or after 784), daughter of Hnabi, Duke of Alamannia.
