Hasson
An Irish surname that is probably a reduced form of an older patronymic meaning “son of Harry/Henry,” though some sources connect it with related Irish forms.
The #9,978 most common surname in the United States (2010 Census) — about 1 in every 95,498 Americans shares it.
Etymology
The name is usually explained as a shortened form of an older patronymic built on a personal name such as Hal, Harry, or Henry, with the sense “son of Hal/Harry.” Some 19th-century Irish references also link Hasson with the Irish form Hassan, suggesting an anglicized Irish surname tradition behind it. Because the early scholarship is brief and partly tentative, the exact pathway is not fully certain.
History
The surname is found in Irish- and Scottish-oriented name lists in the 19th and early 20th centuries, often alongside Hassan. Macbain specifically calls Hasson probably a reduced form of a patronymic, while Woulfe includes it among Irish surname forms. In modern use it appears chiefly in Ireland, Scotland, and countries shaped by Irish and Scottish migration, including the United States.

Fun fact
A 19th-century Scottish surname scholar thought Hasson was probably just a shorter form of “Hal-son,” meaning “son of Hal.”
