Castamir of Umbar

Castamir of Umbar is a Captain of the Corsairs of Umbar who took part in the corsair ambush at Pelargir in the War of the Ring and was killed in Battle.He was probably named after Castamir the ursurper but since Castamir´s last descendants were killed in TA 1810 it seems unlikely that Castamir of Umbar was in any closer relationship to his namesake.Obviously Castamir of Umbar was of Haradrim descent.
