Lords of Ayseau

The Lords of Ayseau(x) (sometimes d'Aysia) belonged to the feudal nobility of Brabant.

History
The title was given to the legitimised son of the Duke of Brabant, and belonged for generations to their descendants. Various important noble houses, amongst them the Brant-family and the house of Ghistel took possession of the dominium. In 1454 Philipp, Duke of Brabant proclaimed that Arnould Brant would have a "rente héreditaire sur la Terre de Grobbendoncq." His brother Jean would inherit the benefits of Grobbendoncq in exchange of the lands of Ayseau.

The dominium was later elevated to a Marchionate in 1626 by King Philip IV of Spain for Rasse of Gavre, 1st Marquess of Ayseaux. The marquess of Ayseau took seat in the Second Estate of Brabant. The families were buried in the Church of Ayseau, where their mausoleum can be found.
