Doyle surname meaning

Doyle is an Irish surname from Ó Dubhghaill, traditionally translated as “descendant of Dubhghall,” or “dark foreigner.” Dubh means dark or black, while gall referred historically to a foreigner, often in contexts involving Norse newcomers. The phrase describes the older personal name, not a modern judgment about Doyle families. Anglicized spelling simplified the Irish structure, and related forms can appear in records under different English spellings. Because the Ó patronymic and its traditional personal-name interpretation are well established, this catalog classifies Doyle as a parent’s-name surname with high confidence.
