Costello (barony)
The Costello family who gave their name to the Barony were originally Nangles, or de Angulos, who came to Connacht with the Anglo Normans in the 12th century.In a number of grants to outlawed Norman lords at this time by Cathal Crobhdearg, King of Connacht, Gilbert and his brothers were given Máenmaige and Cairbre Drom Cliabh.The Costellos were one of the many great Irish families[citation needed] which, during the seventeenth century destruction of everything Gaelic, produced famous rapparees who fought against Oliver Cromwell and the parliamentarians.Returning to Ireland after the Restoration and disappointed by his failure to recover the family estates, he devoted the rest of his life to wreaking vengeance on the new Dillon proprietors until his death in 1667.Loughglynn, built circa 1715, was the seat, or main residence, of the Dillon family in Costello who became absentee landlords in the nineteenth-century.
