History of the Gannon name

Gannon represents Mag Fhionnáin, 'son of Fionnán', a diminutive of fionn, 'fair'. The name belongs above all to County Mayo, where the family was long established in Erris in the far northwest, and it remains most numerous in Mayo and the neighbouring Connacht counties, with a presence in Dublin from the nineteenth century onward. Like many smaller Connacht names it was carried abroad in great numbers during and after the Famine, becoming a familiar surname in Irish communities in Britain and the United States. A proud sporting footnote: Bill 'Squires' Gannon of Kildare was in 1928 the first captain ever to lift the Sam Maguire Cup.
