KEADY Family History

Recorded as Keady and sometimes Keedy, but originally with the Mac or O' prefix, this is an Irish surname. It has it is said, two separate origins. The first claims that it was anciently spelt Mac Ceadaigh, from cead meaning "one hundred". Precisely why anybody or a clan should be called "One hundred" seems to be something of a mystery, and one not explained by any of the authorities on Irish surnames. The name seems today to be most recorded in County Galway, but to have originated in Queens County (now County Leix).
