Halpin
An Irish surname commonly linked to the Gaelic form of Halfpenny, though older sources also treated it as a variant of Harpin.
The #5,886 most common surname in the United States (2010 Census) — about 1 in every 52,642 Americans shares it.
Etymology
Historical sources give two related explanations for Halpin. Irish scholarship, especially Woulfe, connects it with Gaelic forms such as O hAilpin / O hAilpín, and Matheson notes that Halpin and Halfpenny were sometimes used interchangeably in Ireland. Older English surname writers also treated Halpin as a variant of Harpin, but the Irish explanation is the stronger and better-attested one for the name as used in Ireland.
History
The surname is especially associated with Ireland, where it appears in records alongside spellings such as Halpeny and Halfpenny. Nineteenth- and early twentieth-century sources note that some families used Halpin and Halfpenny almost interchangeably in certain districts, showing how fluid the spelling could be. The name also appears in English and American records, where Irish migration likely helped spread it further.
