During the peace negotiations between his father and
Erispoe, duke of
Brittany, Louis was betrothed to a daughter of Erispoe in 856. The daughter's name is not known, nor is it known if this was the same daughter who later married Gurivant. The contract was broken in 857 after Erispoe's murder. Louis was married twice. His first wife
Ansgarde of Burgundy had two sons:
Louis (born in 863) and
Carloman (born in 866), both of whom became kings of
West Francia, and three daughters: Hildegarde (born in 864), Gisela (865–884). By his second wife,
Adelaide of Paris, he had
Ermentrude (874–914) and a posthumous child,
