DAILEY Family History
Recorded as Daily, Dailey, Dayly, Dayley, the original Gaelic O''Dalaigh, the fused French d''Oilly or de Oily, this is a surname of two quite separate origins. The first is Irish and it is reasonable to assume most modern surname holders drive from this source. It means ''The male descendant of Dalach'' deriving from ''dal'' meaning a meeting or assembly. The O'' Dailaigh clan were said to be particularly prominent in Irish history from the 12th to the 18th century, when they featured as poets and bards, writing many of the ancient historical tracts of the period.
