  • Notes 


    • Donnchadh benefited from the introduction of feudal primogeniture as a c u s t o m , as it enabled him and his kin to exclude the descendants of Gill e C r e s t , whose contemporary leader was Thomas de Lundin, from the succe ss i o n . P erhaps in gratitude, he named his oldest son William after King W i l l i a m I, the probable source of the innovation in Mar's inheritance cu s t o m .
