Sheridan anglicises Ó Sirideáin, probably built on sirim, ‘I seek’. The family originated around Togher, in County Longford on the edge of the old kingdom of Breifne, before spreading through Cavan and Longford — a quiet clerical name for centuries until Richard Brinsley Sheridan carried it onto the London stage.
A quiet clerical name for centuries, until Thomas Sheridan and then his grandson Richard Brinsley Sheridan — playwright and one of the sharpest wits in the English language — carried it onto the London stage.
