Adélaïs of Burgundy

Medlands does not at this time support this person profile being attached to currently linked parentage. If she is proven to be a daughter of the mother, then a birth year of 887 does not jive with the mother's birth in December 873.

Louis the blind

Louis III Bosonides, called the blind (* around 881/882; † June 5, 928 in Arles) from the Buvinid family was king of Lower Burgundy from 887 to 928, king of the Lombards (= Italy ) from 900 to 905, which also made him one of the national kings and Roman Emperor 901/902 to 905.

He was the son of Boso of Vienne and his wife Ermengard, a daughter of Emperor Louis II of Italy. After his father's death, as a minor heir, he and his mother paid homage to Emperor Charles the Fat and received his inheritance from him as a fief . Ludwig had the same relationship to Charles's successor, Arnolf von Kärnten.

In 900, Ludwig also became king of the Lombards (= Italy) and in February 901 he was crowned emperor by Pope Benedict IV. In 905 he was defeated by Berengar of Friuli, who blinded him and drove him out of Italy. Count Hugo von Arles became Louis' regent in Lower Burgundy and, after his death in 928, also his successor as king.

Ludwig was married twice. He married his first wife around 900 to Anna of Byzantium (* 886; † before 914), daughter of the Byzantine Emperor Leo VI., his second in 914 with Adelheid of Burgundy, probably a daughter of King Rudolf I of the Guelph family.

From each marriage he had a son:
From Anna: Karl Konstantin (*probably 901; †after January 962) 928/930 Count of Vienne
∞ Teutberga of Troyes (†after 960) Daughter of Count Warnarius and Teutberga of Arles
By Adelheid: Rudolf (†after March 19, 929)
