Haggerty
An Irish surname, often treated as an Anglicized form of a Gaelic family name, though the exact original form is not fully settled.
The #3,194 most common surname in the United States (2010 Census) — about 1 in every 27,274 Americans shares it.
Etymology
Haggerty is generally regarded as an Anglicized Irish surname. Earlier scholarship usually connects it with a Gaelic family name rendered into English spelling in several ways, but the precise original form is not always given consistently in older sources. The ending -erty is typical of many Irish surnames that were reshaped under English spelling conventions.
History
The name is found in Irish and Irish-diaspora records and became established in English-language spelling as families moved through Britain and overseas, especially to North America. Older surname dictionaries often list Haggerty alongside variants such as Haggarty, reflecting the instability of spelling in records. Because the historical excerpts provided do not give a full derivation, the deeper Gaelic source remains somewhat uncertain here.
