surname, from the many Mortons on the map of England, literally "moor or marsh settlement." Morton's Fork (1759) is in reference to John Morton (c. 1420-1500), archbishop of Canterbury, who levied forced loans under Henry VII by arguing the obviously rich could afford to pay and those who were not were living frugally and thus had savings and could pay, too.
