The family name Madden is derived from two Irish roots and one English one. The Madden family of Athgarret in County Kildare are the descendants of an Irish family whose Gaelic name was Ó Madáin. This sept originated in County Galway, in Ireland’s western province of Connacht. They were a branch of a population group known as the Uí Maine (Hy Many in English) whose home territory covered the centre of County Galway, southern parts of County Roscommon and western parts of County Offaly. Their lands were in the Barony of Longford, in south-west Galway, and in the Offaly Barony of Lusnagh, on the other side of the River Shannon from Galway. County Offaly, called Queen’s County during the English administration, is in the Eastern Irish province of Leinster.
