History of the Lenihan name

Lenihan represents two Gaelic families: Ó Leannacháin, a sept of County Roscommon recorded in the medieval annals of Connacht, and a Munster family, Ó Luingeacháin, whose name settled as Lenihan and Linehan in Limerick, Cork and Kerry, with Linehan the usual Cork spelling and Lenihan commoner in Limerick. Maurice Lenihan, the nineteenth-century journalist, wrote the standard Victorian history of Limerick. In modern Ireland the name is inseparable from a formidable political family: Brian Lenihan senior served in governments across four decades, his daughter Mary O'Rourke and sons Brian junior and Conor all held office, with Brian junior steering the Department of Finance through the crash of 2008.
