Quinlan

Etymology

The surname Quinlan is generally taken from an old Irish personal name, though the exact original form is not always spelled consistently in older sources. Irish surname writers connect it with Gaelic forms beginning with O’/Ó and a root like Caoinleán or a related name, suggesting a personal-name origin rather than a place-name or occupation. The broad sense is not certain from the older dictionaries, but it is clearly treated as an inherited Irish family name.

History

Older surname dictionaries place Quinlan among Irish names and note it in both Ireland and the United States. Matheson records it as an established Irish surname by the 18th century, and Woulfe groups it with related Irish forms such as Quinlivan, Kinlan, and Conlan. In English-speaking countries the name often appears in altered spellings, and some forms like Quinland were explained by Bardsley as later expansions of Quinlan.

Fun fact

Nineteenth-century writers sometimes treated Quinland as a mistaken or expanded form of Quinlan rather than a separate surname.
