Irish : reduced Anglicized form of Gaelic Ó Fearadhaigh ‘descendant of Fearadhach’, a personal name of uncertain origin, probably an adjective derivative of fear ‘man’.English : metonymic occupational name for a ferryman, or a topographic name for someone who lived by a ferry crossing on a river. Middle English feri ‘ferry’ is from Old Norse ferja ‘ferry’, ultimately cognate with the Old English verb ferian ‘to carry’.

English : occupational name from Middle English, Old French ferm(i)er (Late Latin firmarius). The term denoted in the first instance a tax farmer, one who undertook the collection of taxes, revenues, and imposts, paying a fixed (Latin firmus) sum for the proceeds, and only secondarily someone who rented land for the purpose of cultivation; it was not applied to an owner of cultivated land before the 17th century.Irish : Anglicized (part translated) form of Gaelic Mac an Scolóige ‘son of the husbandman’, a rare surname of northern and western Ireland.
