Issola tend to serve as diplomats, seneschals of powerful nobles, and entertainers. From 1726 Ahlden House was the residence of the state seneschals. Several Seneschals and Marshals of Brittany belonged to this branch. It audited the royal household, inspectors, royal commissioners, provosts, baillifs, and seneschals. Two other sons were successively seneschals of Gwynedd under Llywelyn ap Gruffudd. In many instances, garrisons or "seneschals" disregarded the law and killed local chiefs and lords. The seneschals also served as the chief justice of the royal courts in their areas.
