Ronan
An Irish and Scottish surname from a personal name linked to saints and a Gaelic word for “seal” or “sea-calf.”
The #8,036 most common surname in the United States (2010 Census) — about 1 in every 74,993 Americans shares it.
Etymology
Ronan comes from a Gaelic personal name, usually understood as a diminutive of a word for “seal” or “sea-calf” (often linked with Irish/Gaelic rin or rón). In later tradition it was strongly associated with saints named Ronan, which helped the name spread as a family surname. The surname therefore began as a name-based form rather than a word describing an occupation or place.
History
The name appears in Irish and Scottish naming traditions, and 19th-century writers often connected it with early saints and legendary figures. It is especially familiar in Ireland and Scotland, with spellings such as Ronayne also recorded in Irish use. The surname is relatively uncommon in the United States today but reflects older Celtic naming patterns.
