The meaning of Morgan

1. Welsh (especially Glamorgan): from the medieval Welsh personal name Morgan, Morgant (Old Welsh Morcant, of uncertain etymology). 2. Irish: importation of the Welsh surname (see 1 above), to which has been assimilated more than one Gaelic surname, notably Ó Muireagáin (see Merrigan). 3. Scottish: probably from a Gaelic personal name cognate with Welsh Morcant. 4. Altered form of Maugans, a surname of German origin. History: Morgan is one of the oldest and commonest of Welsh surnames, but there is also a Scottish family called Morgan, established from medieval times in Aberdeenshire, with connections with the McKays. The Scottish name is probably not the result of Welsh migration, but was established independently. — Abel Morgan (1673–1722), a baptist clergyman, was born in Cardiganshire, South Wales, and emigrated to Philadelphia, PA, in 1712, establishing churches in PA, DE, and NJ. — Some of the American Morgans are descended from the brothers Gabriel and Daniel Morgan, born to Conrad Maugans in MD (see Maugans) c.1779 and 1781, respectively. They died in OH.
