From https://en.wikipedia.org/wiki/Ageltrude

Ageltrude (also spelled Agiltrude) (died 27 August 923) was the Empress and Queen of Italy as wife and mother respectively of Guy (reigned 891–94) and Lambert (reigned 894–98).[1][2] She was the regent for her son and actively encouraged him in opposing her archenemies, the Carolingians, and in influencing papal elections in their favour.

She was the daughter of Prince Adelchis of Benevento and Adeltrude. She married Guy in the early 880s, when he was still just the duke and margrave of Spoleto and Camerino.[1]

From https://en.wikipedia.org/wiki/Adelchis_of_Benevento

Adelchis was the son of Radelchis I, Prince of Benevento, and successor of his brother Radelgar in 854.

It was given to Adelchis to preserve the ancient principality and its independence in the face of repeated assaults by the Saracens from the south, the Emperor Louis II from the north, and Byzantine Langobardia to the east. At first, he was unsuccessful in his wars with the Moslems. He was defeated at Bari in 860 and forced to make a truce with the emir and pay a tribute. In subsequent ventures, he was forced to call in the help of the emperor. In 866, the emperor defeated the Saracens and, in 871, Bari itself fell. Louis then tried to set up greater control over all the south by garrisoning his troops in Beneventan fortresses.

The response of Adelchis to this action was to imprison and rob the emperor while he was staying the princely palace at Benevento in August. A month later, the Saracens had landed with a new invasive force and Adelchis released Louis to lead the armies against it. Adelchis forced Louis to vow never to reenter Benevento with an army or to take revenge for his detention. Louis went to Rome in 872 and was released from his oath by Pope Adrian II on 28 May. He tried to exact punishment on Adelchis, but was not very successful. Adelchis turned to the Byzantines. He was assassinated in May 878.

He was notably the last Lombard ruler to revise the Edictum Rothari.
