Conn
An Irish surname from a Gaelic byname meaning “wise” or “strength,” also linked to the personal name Conn.
The #2,404 most common surname in the United States (2010 Census) — about 1 in every 20,462 Americans shares it.
Etymology
Conn is an Irish surname tied to the old Gaelic personal name Conn. In the historical sources, Conn is explained as meaning either “wise” or “strength,” and it may also be connected with the genitive forms used in patronymic surnames such as O’Quinn (“descendant of Conn”). In some traditions it is also related to words for a dog or to the idea of protection, showing how older Gaelic explanations sometimes overlap.
History
The surname appears in Irish naming traditions and is closely related to surnames like Quinn and O'Quinn, which preserve the older personal name Conn. Because Conn was also used as a given name, the surname can arise either directly from that name or through patronymic forms built from it. Later English-language records often simplified or shortened Gaelic names, helping Conn survive as an independent surname.

Fun fact
The same Gaelic root behind Conn was often glossed in older scholarship as both “wise” and “strength,” which is a good example of how medieval name meanings can be layered and not entirely fixed.
