Fagan Surname Meaning
Irish:: shortened Anglicized form of Gaelic Ó Fágáin or Ó Faodhagáin dialect forms of Ó hÓgáin (see Hogan Hagan) and Ó hAodhagáin (see Hagan). Irish lenited f (spelled fh) is soundless and a number of words beginning with vowels have gained an initial f in some dialects; such seems to be the case here.
Occasionally an Anglicized form of Mac Phaidín (see McFadden) or Ó Fiacháin (see Feehan).
