Aymon's father was Aymar (894-953), sire of Souvigny, his only son with Ermengarde[clarification needed].

Aymar lived during the reign of Charles the Simple who, in 913, gave him fiefs on the river Allier in which would become the Bourbonnais.

She married Guy II of Dampierre, who added Montluçon to the possessions of the lords of Bourbon.

In 1272, Beatrice of Burgundy (1258-1310), Lady of Bourbon, married Robert de France (1256-1318), Count of Clermont, son of king Louis IX (Saint-Louis).

They put their forces at the service of the king, thus benefitting from the geographic position of the Bourbonnais, located between the royal domains and the duchies of Aquitaine and Auvergne.
