After Chlotar's death, King Dagobert I took control of the Frankish Empire and passed over his half-brother Charibert II, who was described as simple-minded in the usual division of the estate.
In 630 Brodulf, who was on his way to Aquitaine, was murdered jointly by Amalgar, the Dux Arnebert and the Patricius Willibad at the instigation of the Frankish king during a stay in Saint-Jean-de-Losne in Burgundy.
[citation needed] After the death of Dagobert I, Amalgar played a central role in the inner-Burgundian power struggle for the underage King Clovis II.
From the marriage came the two sons: Adalrich, who succeeded his father as duke, and Waldelenus, who was taught in the Luxeuil abbey of Columbanus and then worked as abbot of the family monastery of Saint-Pierre, as well as the daughter Adalsind, who became an abbess in Brégille.
[7] The grandson of Amalgar, Adalrich's son Eticho, was a duke in Alsace, father of St. Odilia[8] and ancestor of the noble family, the Etichonids, to which later dynasties, for example the Habsburgs, trace their origin.
