Harty
A surname with Irish and possibly English roots, often linked either to a form of MacCarthy or to a nickname from a word for “hard” or “strong.”
The #8,576 most common surname in the United States (2010 Census) — about 1 in every 80,361 Americans shares it.
Etymology
The surname Harty is most often treated in Irish sources as an Anglicized form connected with MacCarthy, especially in Munster, where shortened or variant forms could develop from the Gaelic family name. Some older writers also connected Harty with a Germanic or English nickname from a root meaning “hard,” “tough,” or “brave.” Because the historical record shows more than one possible line of development, the name may not have a single origin in every family.
History
In Irish genealogical material, Harty appears alongside a cluster of surnames associated with MacCarthy and related forms such as Harrity and Harrington, suggesting regional reduction and anglicization. Matheson’s surname tables group Harty with several other Irish names, reflecting its presence in Ireland as an established family name. Outside Ireland, the name can also appear as an English-looking nickname surname, which may account for independent lines in some records.

Fun fact
A single surname spelling can hide different family origins, and Harty is a good example: some bearers trace to Irish MacCarthy lines, while others may come from a separate nickname tradition.
