Morgan

An Irish surname of Antrim and Dublin. In the 2010 US census it was carried by 286,280 people, the 69th most common surname in the country.

Morgan is the anglicised form of three distinct Irish names. Some you can hear in the English name; others look and sound nothing like it, and were simply swapped for it.

Morgán, son of Morgan (a Welsh personal name)

Ó Muireagáin, descendant of Muireagán (diminutive of some name commencing with Muir-). This family stood in Co. Armagh, Co. Longford, and Co. Westmeath.

Ó Murcháin, descendant of Murchadhán (diminutive of Murchadh, sea-warrior). This family stood in Co. Kildare, Co. Leitrim, and Co. Offaly.

Where the name comes from

Ó Muireagáin was one of the chief families of Teffia, in the present counties of Westmeath and Longford, and were sometimes lords of all that district. About the beginning of the 12th century they disappeared from history and apparently dispersed to different parts of Ireland; by the 16th century the name was most numerous in Down and Armagh. Murrigan, Murricane and Merrigan are the same name.

Morgán, son of Morgan, is the Welsh personal name, and though the surname is fairly common here it is apparently not older than the 16th century.

Antrim

The Antrim coast road runs about 25 miles between the cliffs and the sea, with nine glens coming down to it. The rock is basalt, the same flow that formed the Giant's Causeway. Scotland is 12 miles off at the narrowest point and visible on a clear day.

Dublin

Dublin is a county as well as a city. The bay has Howth at the north end and Killiney Hill at the south, the Muglins are a pair of rocks off Dalkey, and the Dublin Mountains start about half an hour from the city centre.
