Morgan surname meaning
Welsh from the medieval personal name Morcant; Irish Morgan may represent Ó Muireagáin and other streams.
Confidence: Disputed. More than one origin is plausible, or sources disagree. We show the conflict rather than pick a cute answer.
The short story
Morgan is chiefly Welsh, from the medieval personal name Morcant or Morgan. That makes the lead reading a personal-name surname, but not a simple “son of Morgan” formula: the inherited family name preserves the given name itself.
The story widens in Ireland. Morgan can be an imported Welsh surname, and it has also been used as an anglicized form of Ó Muireagáin. Scottish lines may likewise reflect a Gaelic personal name related to Welsh Morcant. Because these streams converge on one spelling without sharing one origin, the page keeps the confidence disputed. The popular “sea-born” gloss is not treated as settled; the older name’s etymology remains uncertain.
