Anselm Marshal
The remarkable extinction of the male line of the Marshall family was credited to a curse bestowed upon the family in 1218 by Bishop of Ferns , Ailbe Ua Maíl Mhuaidh ( died 1223 ) . Each of the five sons of William Marshal , 1st Earl of Pembroke successively inherited the title , but , as Ua Maíl Mhuaidh predicted , none had children and the male line of the family died out .
