Dooley
An Irish surname most often taken from Gaelic roots meaning “sorrowful” or linked to a descendant of a man with a similar Gaelic byname.
The #1,527 most common surname in the United States (2010 Census) — about 1 in every 13,149 Americans shares it.
Etymology
Dooley is usually explained as an Anglicized Irish surname from Gaelic forms written in older sources as O Dublaith or similar spellings. The name is commonly connected with the Gaelic byname Dubhloithe/Dubhloich-type elements, often glossed as “sorrowful” or “melancholy,” though 19th-century writers did not always agree on the exact form. In practice, the surname represents an Irish family name that was reshaped into English spelling over time.
History
The name is well attested in Irish surname lists and appears in several counties in Ireland, especially in the south and east. Emigration carried it to Britain, North America, and other English-speaking countries, where Dooley became the standard modern spelling. Some older reference works also record variant spellings such as Dooly and Dowley.
