Smith is an occupational name and refers to anyone who works with metal, not just blacksmiths. The Gaelic name Mac an Ghabhain translates to “son of the smith.” The name was changed to Smith to appear more English.
Variant spellings include Smithe, Smyth, Smythe, Smithick, and Smythwick. The Smiths in Co. Cavan, where the name first appears in Ireland, were almost all originally MacGowan. Other variants include McGowen and McGowin.
Smith was already a common name by the 1500s in Britain and many who emigrated to Ireland brought the name with them. Many Scottish who later emigrated to Ireland also brought this surname with them. Many Irish Smiths today may be descended from British or Scottish Smith, although many Irish Smiths are not.
In the 1600s the British sought to Anglicize Ireland and many surnames in the Irish language were Anglicized. Many MacGhabhains in County Cavan changed their surname to Smith whereas many MacGhabhains outside the county changed the spelling to their surname to McGowen or MacGowen. In 1890, more than half of the Smiths of Ireland were in Ulster and more than a quarter were in Leinster. The surname was especially common in Antrim, Cavan, and Dublin.
