Dillon Name Meaning
English and French: from the Germanic personal name Dillo (of uncertain origin, perhaps a byname from the root dil ‘destroy’), introduced to Britain from France by the Normans. English: habitational name from Dilwyn near Hereford, recorded in 1138 as Dilun, probably from Old English diglum, dative plural of digle ‘recess’, ‘retreat’, i.e. ‘at the shady or secret places’. Irish (of Norman origin): altered form of de Leon (see Lyon). Irish: reduced Anglicized form of Gaelic Ó Duilleáin ‘descendant of Duilleán’, a personal name, a variant of Dallán meaning ‘little blind one’. Jewish (eastern Ashkenazic): of uncertain origin; either an ornamental name from the Biblical place name Dilon (Joshua 15:38), or an altered form of Sephardic de León (see Lyon).
