Meaning and background

The story behind Reilly

Reilly comes from an Irish surname Anglicized from Ó Raghailligh. Behind the Name traces it to the personal name Raghailleach and explicitly leaves that name's meaning unknown. That is a useful limit: a pleasing English gloss should not be substituted merely because Reilly is familiar. For a dog, a family connection can provide a complete reason for the choice without needing the unresolved older name to have a definite translation.

Origin
From Irish Ó Raghailligh and the personal name Raghailleach, whose meaning is unknown. Source
