OTTO "der Erlauchte", son of Graf LIUDOLF & his wife Oda [Billung] (-30 Nov 912, bur Gandersheim Stiftskirche).

The Annalista Saxo records "Otto" as "filius Liudolfi ducis"[142]. "Hludowicus…rex" granted immunities to Kloster Gandersheim, naming "Brun et Otto nostri fideles comites…[et] Liutolf genitor eorum…[et]…Gerbirg soror eorundem comitum" by charter dated 26 Jan 877[143]. Graf im Südthüringau. "Hludowicus…rex" donated property "Tennisteti et Heriki in pago Suththuringa in comitatu Ottonis" to Kloster Gandersheim by charter dated 26 Jan 877[144]. "Rihdahc" denoted property to Kloster St Maria an der Rosel, in the castle of Coblenz, by undated charter, placed in the compilation with other charters dated [981/89], subscribed by "domini Ottonis Liutolfi filius…"[145].

Graf im Eichsfeld. Emperor Arnulf confirmed an exchange including property "in pago Eichesfelden in comitatu Ottonis" between the abbot of Fulda and "Chunrado comite" on the intervention of "Ottonis…marchionis" by charter dated 28 Jan 897[146].

Lay Abbot of Hersfeld 908. He was chosen to succeed Ludwig "das Kind" [Carolingian] as king of Germany in 911, but declined on the grounds of his advanced age and recommended the election of Konrad ex-Duke of the Franconians[147].

"Chuonradus…rex" confirmed privileges to Kloster Murbach by charter dated 12 Mar 913 with the consent of "fidelium nostrorum Hathonis, Salomonis, Thiodolfi, Hildini, Einhardi, Erchangarii, Chuonradi, Hugonis, Ottonis, Heinrici, Bopponis, Udalrici, Eberhardi"[148].

Thietmar records the death of Otto on 30 Nov but does not give the year[149]. The necrology of Merseburg records the death "30 Nov" of "Oddo comes pater Heinrici regis Saxonum"[150].

m HEDWIG [Hathui], daughter of HEINRICH dux [Babenberg] & his wife Engeltrudis --- ([850/55]-24 Dec 903).

Mistress (1): ---. The name of Otto's mistress is not known.

Graf Otto & his wife had [seven] children:

1. [daughter ([865/70][154]-).

"Wundilgartam Henrici regis de filia neptim" is named in the Chronicle of St Gall, which also names her husband[155]. The commentary in the printed text interprets this as "granddaughter of Heinrich I King of Germany", but this is chronologically impossible assuming that the approximate death date of Wundelgart's husband is correct. If there is any truth in the text, it is more likely that Wundelgart was the niece of King Heinrich by his sister, although this is far from certain considering the broad range of interpretation possible for the word "neptis". However, the chronology is tight even for this interpretation, as shown by the estimated birth date range of this daughter, which must mean that she was one of her parents' older children. Another possibility is that she was illegitimate. The same source in a later passage names "Ekkehardo…diacono et Purchardo puero post abate consobrinis suis"[156]. As Wundelgart was the mother of abbot Burkhard, this gives the essential clue about the name of this daughter's husband, who in the same source is named as the father of the sisters who were mothers of the younger Ekkehard and abbot Burkhard.
m as his first wife, EKKEHARD [I], son of ---.]
2. THANKMAR (-before 30 Nov 912).

"Thancmarus et Liudolfus", sons of Otto & Hathwiga, died before their father according to the Annalista Saxo, which implies they were older than their brother Heinrich who "ecce fratribus defunctis, tota hereditas in ipsum iam ducem derivatur"[157].
3. LIUDOLF (-before 30 Nov 912).

"Thancmarus et Liudolfus", sons of Otto & Hathwiga, died before their father according to the Annalista Saxo, which implies they were older than their brother Heinrich who "ecce fratribus defunctis, tota hereditas in ipsum iam ducem derivatur"[158].
m ---. The name of Liudolf's wife is not known.
Liudolf & his wife had one child.
4. HEINRICH ([876]-Memleben 2 Jul 936, bur Quedlinburg Stiftskirche).

Thietmar records that Heinrich was "born of the noble lineage of Otto and Hadwig"[161]. According to the Annalista Saxo, he was son of the unnamed sister of Adalbert [Babenberg], with whom he and his brothers fought against the Konradiner family, his complete parentage being recorded in a later passage[162].
He was elected as HEINRICH I King of Germany at Fritzlar 6 May 919.
5. ODA ([884][163]-[2 Jul] after 952).

Regino records the marriage in 897 of "Ottonem comitem…filiam Odam" and King Zwentibold[164]. Regino records that "Gerhard comes" married "Odam uxorem Zuendiboldi regis" after killing her first husband in battle in 900[165]. "Otto…rex" confirmed the donation of property " in loco Dauindre…in pago…Hamalant in comitatu Vuigmanni" to St Moritz at Magdeburg by "nostra amita…Uota" by charter dated 30 Dec 952[166]. Jackman speculates[167] that Graf Eberhard married Oda as her third husband, Oda von Sachsen, for onomastic reasons as the name of Eberhard's supposed daughter (her affiliation also being based only on his own separate onomastic hypothesis) was that of Oda's maternal grandmother. This is an interesting theory but it accumulates one onomastic hypothesis on another and must be considered highly speculative.
m firstly ([Worms] [27 Mar/13 Jun] 897) ZWENTIBOLD King of Lotharingia [Carolingian], illegitimate son of Emperor ARNULF King of Germany & his mistress --- ([870/71]-killed in battle 13 Aug 900, bur [Süsteren or Echternach]).
m secondly (900) Graf GERHARD [Matfride], son of --- (-killed in battle 22 Jun 910).
[m thirdly (after Jun 910) EBERHARD Graf im Oberlahngau Pfalzgraf, son of KONRAD Graf in der Wetterau und im Wormsgau [Konradiner] & his wife Glismod --- (-killed in battle near Andernach 23 Oct 939).]
6. LIUTGARD [Dodica] (-21 Jan 923).

Europäische Stammtafeln[168] names Liutgard as daughter of Otto & his wife, but the primary source which confirms this has not so far been identified.
Abbess of Gandersheim 919/923.
7. [IRMINBURG (-before 936).

Europäische Stammtafeln[169] names Irminburg as daughter of Otto & his wife, and records her marriage, but the primary source which confirms this has not so far been identified.
m as his first wife, SIEGFRIED, son of THIETMAR [Ostmark] & his wife --- (-[3 Dec 936/941]).]
Graf Otto had one illegitimate daughter by Mistress (1):

8. daughter. 932.

http://nl.wikipedia.org/wiki/Otto_I_van_Saksen

Otto I van Saksen ( - 13 november 912) was een postume zoon van Ludolf van Saksen en van Hedwig van Friuli. Otto was de eerste die het hertogdom Saksen als erfopvolger bestuurde, namelijk als opvolger van zijn broer Bruno. Hij was Arnulf van Karinthië zeer behulpzaam bij diens Italiaanse krijgstochten en werd de opvoeder van zijn zwager, Lodewijk IV. Na diens dood in 911 werd aan Otto de koningskroon aangeboden, maar hij weigerde wegens zijn leeftijd.

Otto was gehuwd met Hedwig en werd de vader van:

1. Hendrik de Vogelaar 2. Barbara, gehuwd met Hendrik, de stamvader der Oostenrijkse markgraven (volgens andere bronnen de vader van Otto's echtgenote) .

From the English Wikipedia page on Otto the Illustrious:

http://en.wikipedia.org/wiki/Otto_the_Illustrious

Otto or Oddo (c. 851 – 30 November 912), called the Illustrious (der Erlauchte) by later authors, was the Duke of Saxony from 880 to his death. He was the younger son of Liudolf, Duke of Saxony, and his wife Oda, and succeeded his brother Bruno as duke after the latter's death in battle in 880. His dynasty, named after his father, is called the Liudolfing.

By a charter of Louis the Younger to Gandersheim Abbey dated 26 January 877, the pago Suththuringa (country of South Thuringia) is described as in comitatu Ottonis (in Otto's county). In a charter of 28 January 897, Otto is described as marchio and the pago Eichesfelden (Eichsfeld) is now found to be within his county (march). He was also the lay abbot of Hersfeld Abbey in 908. He was described as magni ducis Oddonis (great duke Otto) by Widukind of Corvey when describing the marriage of his sister, Liutgard, to King Louis.

Otto rarely left Saxony. He was a regional prince and his overlords, Louis the Younger and Arnulf, with both of whom he was on good terms, rarely interfered in Saxony. In Saxony, Otto was king in practice and he established himself as tributary ruler over the neighbouring Slav tribes, such as the Daleminzi.

According to Widukind of Corvey, Otto was offered the kingship of East Francia after the death of Louis the Child in 911, but did not accept it on account of his advanced age, instead suggesting Conrad of Franconia. The truthfulness of this report is considered doubtful.[1]

Otto's wife was Hathui (Hedwiga), daughter of Henry of Franconia. Otto was and is buried in the church of Gandersheim Abbey. He had two sons, Thankmar and Liudolf, who predeceased him, but his third son Henry succeeded him as duke of Saxony and was later elected king. His daughter Oda married Zwentibold, King of Lotharingia.

Otto I. (Sachsen)

Otto I., der Erlauchte (* vor 877; † 30. November 912) aus dem Adelsgeschlecht der Liudolfinger war von 880 bis 912 Herzog von Sachsen und von 902 bis 912 Laienabt von Hersfeld.

Leben

Der jüngere Sohn des Grafen Liudolf wurde als Nachfolger seines 880 im Kampf gegen die Wikinger gefallenen Bruders Brun Herzog von Sachsen.

Otto war Graf im Eichsfeld sowie (888) im Südthüringgau und ist 908 als Laienabt von Hersfeld bezeugt. Einer umstrittenen Überlieferung zufolge nahm Otto am Italienzug des Jahres 894 teil, bei dem er zum Kommandanten von Mailand ernannt worden sein soll.

Seine Bedeutung im Machtgefüge des ostfränkischen Reiches zeigt sich darin, dass seine Frau Hadwig aus einer der bedeutendsten Sippen des Reiches stammte und seine Tochter Oda mit einem – wenn auch illegitim geborenen – Mitglied der karolingischen Herrscherfamilie verheiratet wurde.

Otto der Erlauchte wurde in der Kirche des Stiftes Gandersheim bestattet.

Ehe und Nachkommen

Otto war verheiratet mit der fränkischen Babenbergerin Hadwig (Hathui) († 24. Dezember 903), einer Tochter des dux austriacorum Heinrich, mit der er sechs Kinder hatte:

1. Thankmar (907 bezeugt, † vor 30. November 912) 2. Liudolf (907 bezeugt, † vor 30. November 912) 3. Heinrich I. (* 876; † 2. Juli 936), ab 912 Herzog der Sachsen und von 919 bis 936 König des Ostfrankenreiches.

8 906 Hatheburg

8 909 Mathilde die Heilige, Laienäbtissin von Nivelles († 968), Tochter des Grafen Dietrich (Theoderich) aus dem Geschlecht der Immedinger

1. Oda (* 875/880; † wohl 2. Juli nach 952)

8 27. März oder 13. Juni 897 Zwentibold (* 870/871; † 13. August 900), 895–900 König von Lotharingien aus dem Geschlecht der Karolinger

8 Ende 900 Graf Gerhard († 22. Juni 910) aus dem Geschlecht der Matfrieden (Gerhardiner)

1. Liutgard (Dodica) († 21. Januar 923), 919-923 Äbtissin von Gandersheim 2. Irminburg († vor 936) 8 Graf Siegfried († 3. Dezember 936/941), Bruder des Markgrafen Gero

Darüber hinaus hatte Otto eine uneheliche Tochter, deren Name nicht überliefert ist; sie wird im Jahr 932 bezeugt und war mit einem Wido aus Thüringen verheiratet.
