English: habitational name from Markham Clinton or East Markham (Nottinghamshire). The placename derives from Old English mearc ‘mark, boundary’ + hām ‘village, homestead’ or hamm ‘water meadow’.
Irish: English surname used as an equivalent of Gaelic Ó Marcacháin ‘descendant of Marcachán’, a diminutive of Marcach ‘horseman, rider’ (see Markey ). This was originally a Galway surname but is now found mainly in Clare, sometimes translated into English as Ryder .
