==Meaning== As noted further in the source by John O'Hart, though not an occupational surname, MacGowan evolves as an Anglicisation of the original Irish language personal description or nickname , meaning 'blacksmith'. For this reason, the surnames of some septs of the MacGowan are alternately anglicised to Smythe or Smith. The surname MacGowan, therefore, translates from Irish to English as 'son of (the) smith'.
