Welsh (especially Glamorgan): from the medieval Welsh personal name Morgan, Morgant (Old Welsh Morcant, of uncertain etymology).
Irish: importation of the Welsh surname (see 1 above), to which has been assimilated more than one Gaelic surname, notably Ó Muireagáin (see Merrigan ).
Scottish: probably from a Gaelic personal name cognate with Welsh Morcant.
